Attempting to become a #twitter convert. So an #introduction is due I suppose? I'm a scientist (astrophysics) who studies the atmospheres of planets around other stars. Passionate about communication science to the public, particularly when it comes to habitability of exoplanets! Follow me for science, cats, and crafts <3
@_astronoMay Yes I'm sure Dr. Straughn and a few others would be all over this conversion should twitter fall.
NASA could make its own instance and we could have @email@example.com and that would be so cool to have public institutions using public software (while private SpaceX use private Twitter...)
@_astronoMay Habitability of exoplanets? NASA? Results this summer? I don’t think I’ve ever been quicker to hit the follow button. Thanks for being here and welcome aboard! :)
@_astronoMay is that an ERS program? Or did your GO just get lucky enough to be at the start of the schedule?
@thomasconnor ERS program! I think we have the first four exoplanet observations that will be done after commissioning! Our data starts being taken July 10th and we get a transit with a different mode every four days until the 22nd 🤗
The first data from GO programs I'm on is taken on Christmas 🎄
@thomasconnor 😱 I didn't even make that connection! I was just thinking about all the family time I get to "excuse" myself from in order to download our data! 😂
@_astronoMay My day job is looking at the bottom of the sea, but exoplanets geek me up so much 😁 Pleased to make your acquaintance on here, and looking forward to seeing your work!
@_astronoMay Great to see you here. I'm an old "Space Age Kid" myself, watched Armstrong walk on the Moon when I was 12; ended up studying fine art and design, but I still want to be an astronaut when I grow up. Sad, but true.
@_astronoMay I have so many questions. I remember, when studying for my first degree in the 80s, discussing in one of the astrophysics courses, how you could *potentially* detect planets in orbit around other stars. I’m just considering how good the detection equipment needs to be to be able to detect the spectrum lines from non solar planets as they pass in front of their star. Or is there more to it than that?
@cyberspice Yeah, a lot has changed in detector technology since the 80s! The biggest thing is precision! We need detectors that don't generate a lot of noise themselves. But yes, we're essentially detecting the absorption spectrum lines of the atmospheres as they pass in front of the star. These are *really* small signals though! For a jupiter size planet its a few hundred parts per million, for an earth, more like ten parts per million
@_astronoMay That’s what i was thinking. I know how detectors have improved. After my second degree, computing and electronic engineering I ended up working on a bit of the GEO600 gravitational wave detector in the 90s. Presumably you have to also get the stars spectra as a reference. Sounds like kewl stuff. Thanks for answering the question. I ended up in embedded software.
So how about those Trappist exoplanets?
Do you think any might be in a 3/2 or other rotational resonance or are they all face-locked with one side always facing the star? Or chaotic or having some precession due to the nearness of the planets to the star and each other? And somewhat elliptical orbits.
The orbital resonances are beautiful.
Also, is it possible to search for signs of Chlorophyll f?
@hhardy01 They're likely to be tidally locked with one side always facing the star, but we really don't know yet! We can guess based on how long it *should* take a planet like that to lock to its star and how old the system is, which tells us they probably are locked, but until we are able to measure their rotation rates and/or dynamics of their atmospheres we won't know for sure
Welcome to the 'verse @_astronoMay . Keep an eye out for folks on scholar.social. May even be worth setting up an alt account there, I bet their local timeline is gold.
@_astronoMay Yay! I'm excited to learn from you! I'm the telescope operator at CSU Desert Studies Center in Zzyzx.
@_astronoMay Followed. Also an astrophysicist. X-ray binaries. Mostly teaching these days. Guess why I'm leaving Twitter?
