Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems -- A census of oscillating red-giants and main-sequence stars in Gaia DR3 binaries
P. G. Beck, D. H. Grossmann, L. Steinwender +23
Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems containing a oscillating component are interesting…
Magnetic activity evolution of solar-like stars: I. S_ph-Age relation derived from Kepler observations
Savita Mathur, Zachary R. Claytor, Angela R. G. Santos +9
The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archaeology. While ages are usually computed from stellar evolut…
Temporal variation of the photometric magnetic activity for the Sun and Kepler solar-like stars
A. R. G. Santos, S. Mathur, R. A. García +9
The photometric time series of solar-like stars can exhibit rotational modulation due to active regions co-rotating with the stellar surface, allowing us to constrain stellar rotat…
Multi-campaign Asteroseismic Analysis of eight Solar-like pulsating stars observed by the K2 mission
L. González-Cuesta, S. Mathur, R. A. García +11
The NASA K2 mission that succeeded the nominal Kepler mission observed several hundreds of thousands of stars during its operations. While most of the stars were observed in single…
The breakdown of current gyrochronology as evidenced by old coeval stars
Joaquín Silva-Beyer, Diego Godoy-Rivera, Julio Chanamé
Gyrochronology can yield useful ages for field main-sequence stars, a regime where other techniques are problematic. Typically, gyrochronology relations are calibrated using young…
The Origin of Weakened Magnetic Braking in Old Solar Analogs
Travis S. Metcalfe, Adam J. Finley, Oleg Kochukhov +10
The rotation rates of main-sequence stars slow over time as they gradually lose angular momentum to their magnetized stellar winds. The rate of angular momentum loss depends on the…
Rotation Distributions around the Kraft Break with TESS and Kepler: The Influences of Age, Metallicity, and Binarity
Ellis A. Avallone, Jamie N. Tayar, Jennifer L. van Saders +6
Stellar rotation is a complex function of mass, metallicity, and age and can be altered by binarity. To understand the importance of these parameters in main sequence stars, we hav…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
Stellar multiplicity and stellar rotation: Insights from APOGEE
Christine Mazzola Daher, Carles Badenes, Jamie Tayar +18
We measure rotational broadening in spectra taken by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey to characterise the relationship between stellar mul…
Testing the Limits of Precise Subgiant Characterization with APOGEE and Gaia: Opening a Window to Unprecedented Astrophysical Studies
Diego Godoy-Rivera, Jamie Tayar, Marc H. Pinsonneault +6
Given their location on the Hertzsprung-Russell (HR) diagram, thoroughly characterized subgiant stars can place stringent constraints on a wide range of astrophysical problems. Acc…
Stellar Rotation in the Gaia Era: Revised Open Clusters Sequences
Diego Godoy-Rivera, Marc H. Pinsonneault, Luisa M. Rebull
The period versus mass diagrams (i.e., rotational sequences) of open clusters provide crucial constraints for angular momentum evolution studies. However, their memberships are oft…
On the Identification of Wide Binaries in the Kepler Field
Diego Godoy-Rivera, Julio Chanamé
We perform a search for wide binaries in the Kepler field with the prospect of providing new constraints for gyrochronology. First, we construct our base catalog by compiling astro…
The ASAS-SN Bright Supernova Catalog II. 2015
T. W. -S. Holoien, J. S. Brown, K. Z. Stanek +41
This manuscript presents information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during 2015, its second full year of operations. The sam…
The Unexpected, Long-Lasting, UV Rebrightening of the Super-Luminous Supernova ASASSN-15lh
D. Godoy-Rivera, K. Z. Stanek, C. S. Kochanek +11
Given its peak luminosity and early-time spectra, ASASSN-15lh was classified as the most luminous supernova (SN) ever discovered (Dong et al. 2016). Here we report a UV rebrighteni…
ASASSN-15oi: A Rapidly Evolving, Luminous Tidal Disruption Event at 216 Mpc
T. W. -S. Holoien, C. S. Kochanek, J. L. Prieto +17
We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the center of 2MASX J20390918-3045201 ($…
