AB Aur: Investigating a Potential Protoplanet - Special Webinar

Explore the ongoing investigation of a potential protoplanet in AB Aur's circumstellar disk through this informative webinar. Delve into Dr. Lauren Biddle's research combining Hubble Space Telescope observations with ground-based photometry and spectroscopy to study accretion light echoes. Learn about the initial findings from the first observing season and understand how AAVSO members can contribute to this ambitious year-long project. Gain practical insights on effective observation techniques, including optimal filter bandwidths for H-alpha photometry and proper selection of comparison stars. Whether you're an experienced observer or new to the field, this webinar provides valuable information to ensure your observations of AB Aur align with the campaign's objectives and contribute meaningfully to this exciting astronomical research.
