Kepler Image-Subtracted Light Curves and Variable Star Catalog of NGC 6819
Melinda Soares-Furtado, Rianna Kuenzi, Rachel Lee McClure +11
Variable stars in open clusters are valuable probes of stellar evolution. They provide precise measurements of stellar properties, constrain cluster ages and distances, and trace t…
Lithium Enrichment in a Subgiant Star with a Brown Dwarf Companion: A Planetary Engulfment Candidate
Brooke Kotten, Melinda Soares-Furtado, Ricardo Yarza +11
Theoretical models predict that subgiants within a narrow mass regime can retain detectable lithium enrichment signatures from planetary engulfment. We test this prediction using T…
Stars stably accreting from substellar objects
Aaron Householder, Kaitlyn Shin, Kevin B. Burdge +11
Substellar objects such as brown dwarfs and planets are generally expected to remain detached from their main-sequence host stars unless orbital decay or stellar expansion brings t…
Reassessing the Relationship Between Stellar X-ray Luminosity and Age with eROSITA Data Release 1
Nadja Aldarondo Quiñones, Sydney Jenkins, Andrew Vanderburg +2
Accurate stellar dating provides crucial information about the formation and development of planetary systems. Existing age-dating techniques are limited in terms of both the spect…

Starspots on eclipsing giant stars I.: The sample and eclipse mapping examples
K. Oláh, B. Seli, A. Haris +12
Spotted stars in eclipsing binary systems allow us to gather significant information about the stellar surface inhomogeneities that is otherwise impossible from only photometric da…
Asteroseismic Study of Subgiants and Giants of the Open Cluster M67 using Kepler/K2: Expanded Sample and Precise Masses
Claudia Reyes, Dennis Stello, Marc Hon +7
Sparked by the asteroseismic space revolution, ensemble studies have been used to produce empirical relations linking observed seismic properties and fundamental stellar properties…
Planets Around Solar Twins/Analogs (PASTA) I.: High precision stellar chemical abundance for 17 planet-hosting stars and the condensation temperature trend
Qinghui Sun, Sharon Xuesong Wang, Tianjun Gan +30
The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, hi…
A gravitational wave detectable candidate Type Ia supernova progenitor
Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty +37
Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evide…
TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days
Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits +13
We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, Pout, of only 24.5 days. This "eclipses" the previous record set by l…
Confirming the Tidal Tails of the Young Open Cluster Blanco 1 with TESS Rotation Periods
Lizhou Sha, Andrew M. Vanderburg, Luke G. Bouma +1
Blanco 1 is an open cluster located 240 pc from the Sun below the Galactic plane. Recent studies have reported the existence of diffuse tidal tails exte…
Seven new triply eclipsing triple star systems
S. A. Rappaport, T. Borkovits, T. Mitnyan +19
We have identified nearly a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. These systems are noteworthy in that we c…
The Strength and Variability of the Helium 10830 Å Triplet in Young Stars, with Implications for Exosphere Detection
Daniel M. Krolikowski, Adam L. Kraus, Benjamin M. Tofflemire +3
Young exoplanets trace planetary evolution, particularly the atmospheric mass loss that is most dynamic in youth. However, the high activity level of young stars can mask or mimic…
