Alpha Centauri A might host a habitable-zone giant planet. If confirmed, any moons orbiting this planet could be among the most promising nearby locations to search for life. Can we detect those moons by carefully monitoring the position of the planet?

We give this system 3 stars! ⭐⭐⭐
Webb revealed strong evidence of a giant gas planet orbiting one of the three stars (as shown in this artist illustration) in the Alpha Centauri system, located four light years away. go.nasa.gov/3Jmbopa

ALT Graphic titled “NASA's Webb Finds New Evidence for Planet Around Closest Solar Twin.” The background, labeled “artist concept,” shows a large spherical object that looks like a gas giant planet. The object appears to have bands of tan, orange, and dark red horizontal lines forming patterns similar to those in the atmosphere of Jupiter. The background is filled with thousands of distant stars that form a Milky Way-like band running from top left to right. The host star, Alpha Centauri A is a glowing circle near the top left. Further off in the distance above and to the right of the planet is a smaller glowing circle, nearby Alpha Centauri B.

New paper day! And it's on one of our favourite topics, #exomoons! Here's a 🧵summarising our 115 page behemoth of a paper, "An Exomoon Survey of 70 Cool Giant Exoplanets and the New Candidate Kepler-1708 b-i", published today 👇 nature.com/articles/s41550-0…

#VStatePAGET’s Dr. Billy Quarles recently co-authored a paper published in The Astronomical Journal, proposing that if moons that orbit planets exist within Alpha Centauri, they should be detectable with current tech. Read more at phys.org/news/2021-09-earthl… #VState #VStateCoSM

Some more bad news for the recently claimed six exomoons: arxiv.org/abs/2009.14723. Curious how the original paper got so much press but there's so far been no articles on the rebuttals...🤔

Really nice paper by @saturnaxis which uses dynamics to assess the feasibility of exomoon candidates: arxiv.org/pdf/2009.14723.pdf Using tidal and migration constraints, they find that the 6 KOI signals previously ascribed to exomoons can't be explained by stable moons.

@saturnaxis presents his new paper (arxiv.org/pdf/1912.11019.pdf) in which he performs a robust parameter space survey of where circumstellar planets can reside in systems with stellar binaries #DDA51

Marialis Rosario Franco presents work with @saturnaxis in which she shows where within a planetary Hill sphere exomoons can reside, using candidate Kepler-1625b-I as an example. She found that exomoons are generally observationally detectable with a combination of methods #DDA51

Karthik Yadavalli (who works with @astroplum at @GeorgiaTech) presents a great talk in which he describes how we can figure out how seasons change on circumbinary planets #DDA51

The climate on an Earth twin orbiting Alpha Centauri B is especially vulnerable to large changes in obliquity, and a large moon doesn't help. @saturnaxis

As part of camera commissioning, the #TESS science team snapped a two-second test exposure using one of the four @NASA_TESS cameras. A science-quality image, also referred to as a “first light” image, is expected to be released in June. Enjoy this preview! @TESSatMIT
