Dear all,
I hope you will join us for the September LINCC Tech Talk session that will take place on Thursday, September 12, at 10h PT = 13h ET = 13h CLT = 19h CET on Zoom (https://ls.st/lincc-talks ). We will hear from Anastasios Tzanidakis, who will talk about results of a large systematic search for main-sequence dipper stars from ZTF.
A Systematic Search for Main-Sequence Dipper Stars using the Zwicky Transient Facility by Anastasios Tzanidakis
We present results of a large systematic search for main-sequence dipper stars, conducted across a sample of 60 million FGK main-sequence stars using data from Gaia DR3 and the Zwicky Transient Facility (ZTF). Our work introduces a novel light curve scoring algorithm identifying dipper stars, including a scalable workflow for investigating millions of light curves. We have identified at least 60 new intriguing systems, which are now undergoing further investigation to characterize their astrophysical mechanisms, such as occultations by circumstellar debris. This work represents a significant step forward in understanding the frequency and nature of these enigmatic stars, providing important insights into circumstellar environments and planetary evolution. The discoveries from this study will be compiled into the largest open-source catalog of main-sequence dipper stars, laying the groundwork for future multi-wavelength follow-up studies.
LINCC Tech Talks are held on the second Thursday of every month. Events are also advertised at our web page and also provided in calendar form ; and the #lincc-tech-talks LSSTC Slack channel is always available for discussions before, during, and after the talks.
