Chemical Compositions of Red Giant Stars from Habitable Zone Planet Finder Spectroscopy

Christopher Sneden, Melike Afsar, Zeynep Bozkurt +15

We have used the Habitable Zone Planet Finder (HPF) to gather high resolution, high signal-to-noise near-infrared spectra of 13 field red horizontal-branch (RHB) stars, one open-cl…

New Temperature and Metallicity Scale of Cool Giants from K-band Spectra

Supriyo Ghosh, D. K. Ojha, J. P. Ninan

We present here quantitative diagnostic tools for cool giants that employ low-resolution near-infrared spectroscopy in the -band for stellar population studies. In this study, a…

The Habitable-zone Planet Finder Reveals A High Mass and a Low Obliquity for the Young Neptune K2-25b

Gudmundur Stefansson, Suvrath Mahadevan, Marissa Maney +27

Using radial-velocity data from the Habitable-zone Planet Finder, we have measured the mass of the Neptune-sized planet K2-25b, as well as the obliquity of its M4.5-dwarf host star…

A warm Jupiter transiting an M dwarf: A TESS single transit event confirmed with the Habitable-zone Planet Finder

Caleb I. Cañas, Gudmundur Stefansson, Shubham Kanodia +30

We confirm the planetary nature of a warm Jupiter transiting the early M dwarf TOI-1899, using a combination of available TESS photometry; high-precision, near-infrared spectroscop…
