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…
The Active Chromospheres of Lithium-Rich Red Giant Stars
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +17
We have gathered near-infrared -band high resolution spectra of nearly 300 field red giant stars with known lithium abundances in order to survey their \species{He}{i} 1083…
Using Adaptive Experiments to Rapidly Help Students
Angela Zavaleta-Bernuy, Qi Yin Zheng, Hammad Shaikh +4
Adaptive experiments can increase the chance that current students obtain better outcomes from a field experiment of an instructional intervention. In such experiments, the probabi…

Angela Zavaleta-Bernuy, Ziwen Han, Hammad Shaikh +5
Email communication between instructors and students is ubiquitous, and it could be valuable to explore ways of testing out how to make email messages more impactful. This paper ex…
GJ 3929: High Precision Photometric and Doppler Characterization of an Exo-Venus and its Hot, Mini-Neptune-mass Companion
Corey Beard, Paul Robertson, Shubham Kanodia +31
We detail the follow up and characterization of a transiting exo-Venus identified by TESS, GJ 3929b, (TOI-2013b) and its non-transiting companion planet, GJ 3929c (TOI-2013c). GJ 3…
A close-in puffy Neptune with hidden friends: The enigma of TOI 620
Michael A. Reefe, Rafael Luque, Eric Gaidos +82
We present the validation of a transiting low-density exoplanet orbiting the M2.5 dwarf TOI 620 discovered by the NASA TESS mission. We utilize photometric data from both TESS and…
