SUMMARY:Taking the Pulse of the Stars
DESCRIPTION:By measuring changes in light output on many different timescales\, we can detect and analyze a myriad of phenomena\, from stellar rotation to the dynamics of nascent exoplanet systems. While most stars are too far away for us to “see” what is going on at or around their surfaces\, time domain studies provide access to these close-in regions. \nZoom | Register

SUMMARY:TFOP: Contributing to TESS Exoplanet Discoveries
DESCRIPTION:With seven years of observations covering most of the sky already completed\, the Transiting Exoplanet Survey Satellite (TESS) continues to identify new\, exciting\, and unique planet candidates. After identification by TESS\, ground-based observations\, organized by the TFOP leads\, are required to confirm the planetary nature of a candidate or discard it as a false positive. Dr. Karen Collins will provide an overview of the TFOP program\, demonstrate the tools made available to coordinate and analyze observations by citizen\, student\, and professional astronomers from around the world\, and explain how to apply to join the fun. \nKaren Collins is an Astronomer at the Center for Astrophysics | Harvard & Smithsonian\, and she leads the TFOP ground-based transit observing team.

SUMMARY:Pandora’s Box: How NASA and Citizen Scientists Help Avert Disaster
DESCRIPTION:Last month\, Dr. Waalkes gave a presentation on how stellar activity could drastically alter the interpretation of an exoplanet’s atmospheric composition. This month\, join Dr. Rob Zellem (NASA Goddard Space Flight Center) as he talks about NASA’s Pandora SmallSat mission\, which is scheduled to launch no earlier than Fall 2025 and will monitor ≥20 transiting exoplanets and their host stars to disentangle stellar activity from the planet’s atmospheric signal. Pandora’s efforts will help enhance the science returns of NASA missions like Hubble and JWST. He will also present how citizen scientists and amateur astronomers can become involved and already are directly contributing to the Pandora mission and other NASA efforts.

SUMMARY:M Dwarf Starspots & Transiting Exoplanets
DESCRIPTION:The discovery and characterization of exoplanet atmospheres is mired in the challenge of disentangling planetary characteristics from the complex signatures of stellar activity. For stars cooler than the Sun\, spots on their surface can be cool enough that molecular absorption appears in the stellar spectrum and can be mistaken for absorption in a planetary atmosphere. Will’s research addresses this with a combination of space- and ground-based observations of M dwarfs with transiting planets\, focusing on modeling the stellar photosphere alongside the transit. In this talk\, Will discusses the challenges of understanding planets transiting spotted stars\, and the role that multi-color photometry plays in characterizing starspots.

SUMMARY:Practice Makes Perfect: Getting Ready for the Next Galactic Supernova
DESCRIPTION:Professor Dan Milisavljevic (Purdue University) will review and update plans for a coordinated global response to the next supernova in our Milky Way galaxy. The first alert that the “Big One” has happened will come from the Supernova Early Warning System (SNEWS)\, which is a network of neutrino detectors around the world. The neutrinos will arrive minutes to hours ahead of the first photons\, which gives observers little time to locate and monitor the star as the explosion is happening.

SUMMARY:Things I Thought I’d Never See
DESCRIPTION:Bob King fell in love with the night sky when he was a kid\, and he loves to share his passion with people of all ages through teaching and public observing. His long-time association with the AAVSO has seen him observe the most remote and exotic places in the universe—including “visits” to quasars\, blazars and supernovae. In this webinar\, Bob will demonstrate techniques for coaxing out faint transients near the limit of vision or shrouded in extragalactic haze. He’ll also discuss the importance of using up-to-date charts\, photographs and websites to assist in the quest to see the ends of the cosmos. \nBob is a community educator and writes for Sky & Telescope’s magazine and website. He also pens the long-time blog Astro Bob he started in 2008\, and has been an AAVSO member since 1982.

SUMMARY:Introduction to Exoplanet Observing
DESCRIPTION:Interested in learning how to detect a planet orbiting a distant star? And doing so from your own backyard telescope? This webinar will provide an overview of the instrumentation\, software\, and processes required to detect exoplanets using the transit method. For astro-imagers in particular\, the transition to exoplanet observing offers an opportunity to use your acquired skills and equipment to advance exoplanet research\, while adding new excitement to your observing\nexperiences. \nAlthough amateur astronomers have conducted their own exoplanet observations for several years\, their contributions to recent NASA exoplanet missions such as TESS have been particularly impactful. We’ll review how you can be part of a team with professional astronomers discovering new worlds outside our solar system.

SUMMARY:Sections in the Spotlight: Solar\, EBs and LPVs
DESCRIPTION:This webinar will feature brief talks from three AAVSO Sections: Solar Observing\, Eclipsing Binaries\, and Long Period Variables. \nThe session will include a discussion of the AAVSO’s Section system\, and ways to participate. \nBe sure to stick around for the interactive Q&A with the Sections’ leaders! \nWhat is a Section?\nAAVSO Sections are groups of volunteers united in the study of a particular topic\, such as exploding stars or precision spectroscopy. Sections provide opportunities to learn\, socialize\, and contribute to science.

SUMMARY:Photometry: Transformations and Filters
DESCRIPTION:Join Dr. Brian Kloppenborg\, AAVSO’s Executive Director\, as he traces the journey of light from the stars to our sensors. \nThe presentation will explore the impacts atmospheric transmission\, telescope optics\, and sensor technologies have on stellar photometric data\, as well as how photometric filters and transformation processes serve to standardize measurements across observers. \nBrian will discuss the most common photometric systems used by amateur astronomers\, present transmission curves of a variety of commercially available filters\, and discuss how you can use transformation to improve the quality of your photometry.

SUMMARY:Cataclysmic Variables
DESCRIPTION:While all cataclysmic variables contain the same basic component stars (a white dwarf and a close companion)\, they can appear very different depending on individual properties like magnetic fields\, accretion state\, evolution state and companion type. This webinar will describe the various photometric and spectroscopic behavior that has been observed\, which ones are well understood and what observations are still needed to complete our understanding of these systems.

SUMMARY:Asteroseismology: Golden Opportunities for Astrophysics
DESCRIPTION:Asteroseismology has been bringing breakthrough science for more than a decade. In this webinar\, 2022 Kavli laureate Conny Aerts will introduce the basic principles of asteroseismology and explain its capacity to probe stellar interiors. It will be shown how applications to sun-like stars and red giants feed exoplanetary and galactic science. \nThe talk will then focus on more recent applications to stars rotating much faster than the Sun. We discuss how gravito-inertial asteroseismology offers to estimate the internal rotation and chemical mixing deep inside stars\, with major implications for stellar evolution. We end with exciting future opportunities for this booming research field of astrophysics from the future ESA PLATO space mission under construction.

SUMMARY:Introductory Photometry
DESCRIPTION:We’re kicking off the new year with a webinar on one of our most popular topics—photometry! Whether you’re new to variable star observing or you’re an old-timer looking for ways to improve your photometric precision\, this event is for you. \nWe’ll demonstrate the process of photometric reduction\, discuss important topics such as binning and choice of filters\, and share how you can maximize your photometric accuracy. Afterwards\, we’ll wrap up with an extended Q&A session\, giving attendees the opportunity to ask an expert for advice on all of your burning questions about photometry\, no matter how specific.
