To Separate Starspots from Planets When it comes to M dwarfs, how do you distinguish between starspots and planets? aasnova.org/2020/10/02/to-se… @UCIPhysAstro
Three planets orbit a dim, red star, which is center-left in the image. One planet sits prominently to the left in the foreground. The foreground planet has features reminiscent of clouds.

The discovery of a Jupiter-sized planet transiting an M dwarf star — made by a team including Eberly's Caleb Cañas, @gummiks, @shubhamkanodia, @SuvrathM, and @Astro_Wright — could help astronomers better understand how these planets form. buff.ly/33r7XoK @HPFspectrograph

⚠️New paper⚠️ led by Caleb Cañas @PSUScience: using precision radial velocities from @HPFspectrograph, we confirm the planetary nature of TOI-1899b, the first Warm Jupiter (Period~29days) orbiting an early M-dwarf star as observed by @NASA_TESS !

Exciting new @HPFspectrograph planet paper led by @shubhamkanodia on TOI-1728b, a super-Neptune orbiting a nearby bright M0 star, and a promising @JWSTObserver target! Paper discusses mass measurement, ground-based transits (#diffusers), He 10830 absorption constraints, and more!

A Mini-Neptune and a Venus-Zone Planet in the Radius Valley...

We report on the validation of two planets orbiting the nearby (36pc) M2 dwarf TOI-1266 observed by the TESS mission. The inner planet is sub-Neptune-sized ($R=2.46 \pm 0.08 R_\oplus$) with an...

Guess what the image in the lower right corner is in this tweet from NIST. Its our Habitable-zone Planet Finder (HPF) spectrometer on the 10m Hobby Eberly Telescope! (its primary calibration source is a frequency stabilized laser comb). @HPFspectrograph @NIST @mcdonaldobs

The future is here! NIR RV precision breaks 3 m/s! Metcalf et al. arxiv.org/abs/1902.00500 @HPFspectrograph I knew it would work! So happy.

One of the most important piece of info from her talk: @HPFspectrograph is doing 1.3 m/s over several weeks on a real target!!! State of the art of NIR PRV is upon us! xitter.gq/johannateske/status/10…

Replying to @johannateske
Arpita Roy is now digging into the nitty gritty details of RV data reduction and analysis. She emphasizes that at <1 m/s level, need to gather the right info when observing to make good analysis possible. Beautiful example of data from @HPFspectrograph! #sagan2018
