The Habitable Zone Planet Finder instrument was delivered to the Hobby-Eberly Telescope (HET) in late 2017 and started full science operations in late 2018. [3] The tower next to the telescope, called the Center of Curvature Alignment Sensor Tower (CCAS), is used to calibrate the mirror segments. “Using HPF, we are currently surveying the nearest low-mass stars — also called M-dwarfs, which are the most common stars in the galaxy — with the goal of discovering exoplanets in our stellar neighborhood,” said Suvrath Mahadevan, professor of astronomy and astrophysics at Penn State and principal investigator of the HPF spectrograph. Disturbances created sound waves that rippled across the dense universe. The exciting new discovery, called G 9-40b, was validated using an astronomical spectrograph built by a Penn State team with the help of UNC-Chapel Hill’s Goodman Laboratory, led by Chris Clemens, stellar astrophysicist and senior associate dean for research and innovation in the College of Arts & Sciences. The Habitable-zone Planet Finder was delivered to the 10m Hobby Eberly Telescope at McDonald Observatory in late 2017, and started full science operations in late 2018.

The Hobby–Eberly Telescope (HET) is a 10-meter (30-foot) aperture telescope located at the McDonald Observatory in Davis Mountains, Texas. “In this instrument, the lab produced an optic called a ‘cross-dispersing grism’ that increased the overall efficiency and performance of the instrument.”. UNC-Chapel Hill made important contributions to the HPF spectrograph. “G 9-40b is amongst the top 20 closest transiting planets known, which makes this discovery really exciting,” said Guðmundur Stefánsson, lead author of the paper and a former Ph.D. student at Penn State who is currently a postdoctoral fellow at Princeton University. Gelatin, which comes from cows, is pretty cheap,” Clemens said. [2][3] The telescope is named for former Texas Lieutenant-Governor Bill Hobby and for Robert E. Eberly, a Penn State benefactor. All three instruments are spectrographs. Furthermore, the telescope's main mirror is fixed at a 55° angle and can rotate around its base. For instance, the primary mirror is constructed from 91 hexagonal segments, which is less expensive than manufacturing a single large primary. Lua error in Module:Wikidata at line 446: attempt to index field 'wikibase' (a nil value). The HPF provides the highest precision measurements to date of infrared signals from nearby low-mass stars, and astronomers used it to validate the candidate planet by excluding all possibilities of contaminating signals to very high level of probability. A publicly accessible discussion of this result can also be found on the HPF blog. HETDEX will study baryonic acoustic oscillations— "sound waves" from the first 400,000 years of the universe. HPF was delivered to the 10m Hobby-Eberly Telescope at McDonald Observatory in late 2017 and started full science operations in late 2018.
