Celebrations of the First light of our High Resolution mode at HET!

[HPF @HPFspectrograph]

This was a huge collaborative effort, including partnership with HPF's sister spectrograph, @NEID_at_WIYN. Key participants include @mcdonaldobs @NOIRLabAstro @SuvrathM @gummiks @LubysLemmas

We have discovered a super-Earth in the Habitable Zone of a very nearby star, GJ 251. The system is close enough to us that it could potentially be imaged by upcoming 30-meter telescopes. Study led by HPF team member Corey Beard https://t.co/K7L872hO6q

Exciting new HPF result led by @gummiks: radial velocities confirm the first astrometric exoplanet discoveries from Gaia! Post on the HPF blog: https://t.co/x9Y6AWB0If

⚠️New paper!⚠️ We have discovered a planet, Gaia-4b, and a brown dwarf, Gaia-5b, using the @ESAGaia spacecraft. Gaia-4b is Gaia's first planet detected with astrometry alone and represents the tip-of-the-iceberg of the 100s-1000s of planets that Gaia is expected to detect.

[HPF @HPFspectrograph]

Our paper describing the discovery appears in Science today, and was led by @gummiks. h/t to @mcdonaldobs

Big announcement on the HPF blog: our HPF exoplanet survey has discovered a Neptune-mass exoplanet on a close-in orbit around a very low-mass star. This planet challenges our understanding of planet formation around low-mass stars: https://t.co/NseJWJPqOJ

Is a Neptune Desert still a desert if it's not as hot? Not according to this new HPF result! Check out the new blog post. Work led by HPF team members Luke Powers and Jessica Libby-Roberts. https://t.co/YkAAKxG2tq

[HPF @HPFspectrograph]

Newon the HPF blog: some history--and a new exoplanet discovery--from the original @mcdonaldobs M dwarf planet search. Data from @keckobservatory helped confirm the orbit, and astrometry gives a *true mass* for the planet! https://t.co/k4feU0ynhA

New science on the HPF blog: check out how a transiting planet helps us study massive polar starspots on TOI-3884! Post and research led by Jessica Libby-Roberts https://t.co/3lRDd9MAo2

Joint gathering of the NEID and @HPFspectrograph teams at #EPRV5. Exciting to have such a talented and growing team!

Can a planet be too big to exist? Maybe not, but it can certainly be too big for planet formation theories to readily explain! Check out the new result from HPF at @mcdonaldobs and @NASA_TESS, led by @shubhamkanodia.

Congratulations to Shubham Kanodia and Caleb Cañas on their successful Ph.D defenses this week! @HPFspectrograph @NEID_at_WIYN @AstroPSU @shubhamkanodia

[HPF @HPFspectrograph]

HPF studies really small stars all the time, but how about really small planets orbiting really close to those really small stars? New result from Caleb Cañas and the team: https://t.co/Rr1d0nU7OY
