I Spy Transits and Pulsations: Empirical Variability in White Dwarfs Using Gaia and the Zwicky Transient Facility
Joseph A. Guidry, Zachary P. Vanderbosch, J. J. Hermes +13
We present a novel method to detect variable astrophysical objects and transient phenomena using anomalous excess scatter in repeated measurements from public catalogs of Gaia DR2…
The luminous red nova variety: AT 2020hat and AT 2020kog
A. Pastorello, G. Valerin, M. Fraser +32
We present the results of our monitoring campaigns of the luminous red novae (LRNe) AT 2020hat in NGC 5068 and AT 2020kog in NGC 6106. The two objects were imaged (and detected) be…
When Do Stalled Stars Resume Spinning Down? Advancing Gyrochronology with Ruprecht 147
Jason Lee Curtis, Marcel A. Agüeros, Sean P. Matt +17
Recent measurements of rotation periods () in the benchmark open clusters Praesepe (670 Myr), NGC 6811 (1 Gyr), and NGC 752 (1.4 Gyr) demonstrate that, after convergi…
EvryFlare III: Temperature Evolution and Habitability Impacts of Dozens of Superflares Observed Simultaneously by Evryscope and TESS
Ward S. Howard, Hank Corbett, Nicholas M. Law +8
Superflares may provide the dominant source of biologically relevant UV radiation to rocky habitable zone M-dwarf planets (M-Earths), altering planetary atmospheres and conditions…
Gaia18aen: First symbiotic star discovered by Gaia
J. Merc, J. Mikołajewska, M. Gromadzki +20
Besides the astrometric mission of the Gaia satellite, its repeated and high-precision measurements serve also as an all-sky photometric transient survey. The sudden brightenings o…
EVR-CB-004: An Inflated Hot Subdwarf O star + Unseen WD Companion in a Compact Binary Discovered with the Evryscope
Jeffrey K. Ratzloff, Thomas Kupfer, Brad N. Barlow +10
We present the discovery of EVR-CB-004, a close binary with a remnant stellar core and an unseen white dwarf companion. The analysis in this work reveals the primary is potentially…
TOI-811b and TOI-852b: New transiting brown dwarfs with similar masses and very different radii and ages from the TESS mission
Theron W. Carmichael, Samuel N. Quinn, George Zhou +17
We report the discovery of two transiting brown dwarfs (BDs), TOI-811b and TOI-852b, from NASA's Transiting Exoplanet Survey Satellite mission. These two transiting BDs have simila…
The Tau Association: A 60 Myr-Old Coeval Group at 150 pc from the Sun
Jonathan Gagné, Trevor J. David, Eric E. Mamajek +3
[Abbreviated] We present an analysis of the newly identified Tau Association (MUTA) of young stars at 150 pc from the Sun that is part of the large Cas-Tau structure, co…
Evryscope-South Survey of Upper- and Pre-main Sequence Solar Neighborhood Stars
Nathan W. Galliher, Jeffrey K. Ratzloff, Henry Corbett +5
Using photometric data collected by Evryscope-South, we search for nearby young variable systems on the upper-main sequence (UMS) and pre-main sequence (PMS). The Evryscopes are al…
TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars
Ismael Mireles, Avi Shporer, Nolan Grieves +40
We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exo…
TIC 278956474: Two close binaries in one young quadruple system, identified by \textit{TESS}
Pamela Rowden, Tamás Borkovits, Jon M. Jenkins +25
We have identified a quadruple system with two close eclipsing binaries in TESS data. The object is unresolved in Gaia and appears as a single source at parallax 1.08~0.01 mas…
Very regular high-frequency pulsation modes in young intermediate-mass stars
Timothy R. Bedding, Simon J. Murphy, Daniel R. Hey +33
Asteroseismology is a powerful tool for probing the internal structures of stars by using their natural pulsation frequencies. It relies on identifying sequences of pulsation modes…
Orbital Parameter Determination for Wide Stellar Binary Systems in the Age of Gaia
Logan A. Pearce, Adam L. Kraus, Trent J. Dupuy +4
The orbits of binary stars and planets, particularly eccentricities and inclinations, encode the angular momentum within these systems. Within stellar multiple systems, the magnitu…
Angular Momenta, Magnetization, and Accretion of Protostellar Cores
Aleksandra Kuznetsova, Lee Hartmann, Fabian Heitsch
Building on our previous hydrodynamic study of the angular momenta of cloud cores formed during gravitational collapse of star-forming molecular gas in our previous work, we now ex…
An Isolated White Dwarf with 317-Second Rotation and Magnetic Emission
Joshua S. Reding, J. J. Hermes, Z. Vanderbosch +5
We report the discovery of short-period photometric variability and modulated Zeeman-split hydrogen emission in SDSSJ125230.93-023417.72 (EPIC 228939929), a variable white dwarf st…
Two intermediate-mass transiting brown dwarfs from the TESS mission
Theron W. Carmichael, Samuel N. Quinn, Alexander J. Mustill +28
We report the discovery of two intermediate-mass brown dwarfs (BDs), TOI-569b and TOI-1406b, from NASA's Transiting Exoplanet Survey Satellite mission. TOI-569b has an orbital peri…
