Searching for GEMS: Discovery of the Nearby Post-Common-Envelope Binary System TIC-460388167
Alexandra Boone, Henry A. Kobulnicky, Caleb I. Cañas +11
Short-period white dwarf+main-sequence binaries are Post-Common-Envelope Binaries (PCEB) that have survived a common envelope phase. Such systems, if detached and eclipsing, enable…
A Chemical Mismatch Between Young Stars and Their Inner Disks
Diogo Souto, Ilaria Pascucci, Katia Cunha +1
We present the first stellar elemental abundance study for two very low-mass stars, similar in mass to TRAPPIST-1, in the \,Myr-old Upper-Sco association. Their mid-infra…
Stellar and orbital characterization of three low mass M dwarf binary stars with dynamical spectroscopy from the Habitable Zone Planet Finder
Suhani Surana, Chad F. Bender, Caleb I. Cañas +13
Theoretical models of low-mass stars continue to be discrepant with observations when used to examine the mass-radius relationship and other physical parameters of individual stars…
NEIDSpecMatch: stellar parameter estimation with NEID spectra using an empirical library
Te Han, Paul Robertson, Caleb I. Cañas +16
We introduce NEIDSpecMatch, a tool developed to extract stellar parameters from spectra obtained with the NEID spectrograph. NEIDSpecMatch is based on SpecMatch-Emp and HPFSpecMatc…
Earths within Reach: Evaluation of Strategies for Mitigating Solar Variability using 3.5 years of NEID Sun-as-a-Star Observations
Eric B. Ford, Chad F. Bender, Cullen H. Blake +15
We present the results of Sun-as-a-star observations by the NEID Solar Telescope at WIYN Observatory, spanning January 1, 2021 through June 30, 2024. We identify 117,060 observatio…
Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby Eccentric Brown Dwarf LHS 1610 b
Evan Fitzmaurice, Gudmundur Stefánsson, Robert D. Kavanagh +18
The LHS 1610 system consists of a nearby ( pc) M5 dwarf hosting a candidate brown dwarf companion in a day, eccentric () orbit. We confirm this brown dwa…
TOI-5375 B: A Very Low Mass Star at the Hydrogen-Burning Limit Orbiting an Early M-type Star
Mika Lambert, Chad F. Bender, Shubham Kanodia +16
The TESS mission detected a companion orbiting TIC 71268730, categorized it as a planet candidate, and designated the system TOI-5375. Our follow-up analysis using radial velocity…
Detection of p-mode Oscillations in HD 35833 with NEID and TESS
Arvind F. Gupta, Jacob K. Luhn, Jason T. Wright +15
We report the results of observations of p-mode oscillations in the G0 subgiant star HD 35833 in both radial velocities and photometry with NEID and TESS, respectively. We achieve…
Rotational modulation of spectroscopic Zeeman signatures in low-mass stars
Ryan C. Terrien, Allison Keen, Katy Oda +24
Accurate tracers of the stellar magnetic field and rotation are cornerstones for the study of M dwarfs and for reliable detection and characterization of their exoplanetary compani…
An eccentric Brown Dwarf eclipsing an M dwarf
Caleb I. Cañas, Suvrath Mahadevan, Chad F. Bender +16
We report the discovery of a brown dwarf transiting the early M dwarf TOI-2119 on an eccentric orbit () at an orbital period of $7.2008…
Gaia 20eae: A newly discovered episodically accreting young star
Arpan Ghosh, Saurabh Sharma, Joe. P. Ninan +18
The Gaia Alert System issued an alert on 2020 August 28, on Gaia 20eae when its light curve showed a 4.25 magnitude outburst. We present multi-wavelength photometric and spec…
High resolution near-infrared spectroscopy of a flare around the ultracool dwarf vB 10
Shubham Kanodia, Lawrence W. Ramsey, Marissa Maney +20
We present high-resolution observations of a flaring event in the M8 dwarf vB 10 using the near-infrared Habitable zone Planet Finder (HPF) spectrograph on the Hobby Eberly Telesco…
Persistent starspot signals on M dwarfs: multi-wavelength Doppler observations with the Habitable-zone Planet Finder and Keck/HIRES
Paul Robertson, Gudmundur Stefansson, Suvrath Mahadevan +23
Young, rapidly-rotating M dwarfs exhibit prominent starspots, which create quasiperiodic signals in their photometric and Doppler spectroscopic measurements. The periodic Doppler s…
