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 hpf.psu.edu/2025/10/23/gj2…

Exciting new HPF result led by @gummiks: radial velocities confirm the first astrometric exoplanet discoveries from Gaia! Post on the HPF blog: sites.psu.edu/hzpf/2025/02/0…

⚠️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.

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: sites.psu.edu/hzpf/2023/11/3…

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! sites.psu.edu/hzpf/2023/06/1…

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.
