🚨Terrible pun alert: Fur-midable Candidate! 🚨 Spotted on Talk: a lightcurve with cat ears!🐱 Our sharp-eyed moderator
@cosmosbg.bsky.social also noticed periodic dips, suggesting a potential new eclipsing binary candidate.
As our teammate Marco says, maybe there are space kittens out there! 🐈

2/2:In eccentric EBs, the primary-to-secondary separation varies based on our viewing angle of the ellipse. This makes their lightcurves more intricate- the trigonometry behind it all is truly interesting! Shout to this tool midnightkite.com/index.aspx?U... Shared by@davideiannone.bsky.social

1/2: Shoutout to a fascinating Talk discussion on eccentric eclipsing binaries (EBs)! For circular EBs, the time between primary and secondary eclipses is half the binary period. But for eccentric EBs, it’s more complex due to their elliptical orbits. (Continues…)
#EclipsingBinaryPatrol

Happy 2025 from the Eclipsing Binary Patrol team! ✨
Thank you to everyone who continued classifying over the holidays. You identified a fascinating candidate: a possible new eclipsing binary—maybe even a heartbeat star! Here’s to a year with yet more discoveries! 🚀

⭐️The Eclipsing Binary Patrol project will have reduced coverage on the Talk board over the holiday season.
We’ll still be around but may take longer to reply. We hope you’ll continue participating actively, we love seeing your contributions⭐️
*looks for a Xmas tree shaped lightcurve to post…fails*

This holiday season, don’t forget that Citizen Science can bring joy and free entertainment 🥂🥳 It’s fun, easy and rewarding, and screen time = meaningful action 🤩Happy classifying!

Some cheer for the season:
In eclipsing binaries, lightcurves show regular dips as stars eclipse each other. With circumbinary planets (CBPs), lightcurves get complex: planetary dips plus the binary’s eclipses create a mix of periodic/irregular patterns. Those may be lurking in our EB Patrol data! 🔍

Shoutout to a crossover project alert! A volunteer on the Black Hole Hunters project proactively identified potential eclipsing binary candidates while analyzing TESS lightcurves. Science thrives on these unexpected connections! @adammc.space @blackholehunters.bsky.social

We just hit the 3-month mark for our project, and an incredible milestone of 10k completed (fully classified) subjects - that’s amazing progress! 💫

Thank you to all the citizen scientists who have joined us so far in looking for eclipsing binary stars!

Did you know some eclipsing binary stars have incredibly short orbital periods? 🌌 For example, this system of two white dwarfs completes an orbit in just 6.9 minutes! 🔭 Check out the research here: ui.adsabs.harvard.edu/abs/2019hst....

A great example of why we need YOUR help to check the data! Look closely at the light curve, and you’ll spot small regular eclipses just right of the green bands. This is an EB with synchronized baseline modulations and the period needs recalculating

Hello Citizen Scientists! We launched our new project with the Zooniverse platform in Sept and we’ve already reached >150k classifications! We are looking at TESS data in search for Eclipsing Binary stars - and we need your help to find genuine candidates ! Link in the bio
