We present a detailed analysis of the asteroseismic main-sequence benchmark star Dra A in the TESS northern CVZ. We aim to derive stellar mass and radius from asteroseismic mod…
Asteroseismic Analysis of the Merger Product Red Giant in the Persei System
Rozália Z. Ádám, László Molnár, Róbert Szabó +7
Context. Persei is a long-period eclipsing binary system ( years) containing a red giant primary, and it is well known for its multi-faceted classification as a…
Testing the Rossby Paradigm: Weakened Magnetic Braking in early K-type Stars
Travis S. Metcalfe, Pascal Petit, Jennifer L. van Saders +12
There is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds…
The K2 Asteroseismic KEYSTONE sample of Dwarf and Subgiant Solar-Like Oscillators. I: Data and Asteroseismic parameters
Mikkel N. Lund, Sarbani Basu, Allyson Bieryla +19
The KEYSTONE project aims to enhance our understanding of solar-like oscillators by delivering a catalogue of global asteroseismic parameters ( and ) for 173 s…
Fundamental stellar parameters of benchmark stars from CHARA interferometry -- III. Giant and subgiant stars
I. Karovicova, T. R. White, T. Nordlander +3
Large spectroscopic surveys of the Milky Way need to be calibrated against a sample of benchmark stars to ensure the reliable determination of atmospheric parameters. We present ne…
Fundamental stellar parameters of benchmark stars from CHARA interferometry -- II. Dwarf stars
I. Karovicova, T. R. White, T. Nordlander +3
Stellar models applied to large stellar surveys of the Milky Way need to be properly tested against a sample of stars with highly reliable fundamental stellar parameters. We have e…
Detections of solar-like oscillations in dwarfs and subgiants with Kepler DR25 short-cadence data
S. Mathur, R. A. García, S. N. Breton +6
During the survey phase of the Kepler mission, several thousands of stars were observed in short cadence, allowing the detection of solar-like oscillations in more than 500 main-se…
K2 photometry and HERMES spectroscopy of the blue supergiant rho Leo: rotational wind modulation and low-frequency waves
C. Aerts, D. M. Bowman, S. Simon-Diaz +10
We present an 80-d long uninterrupted high-cadence K2 light curve of the B1Iab supergiant rho Leo (HD 91316), deduced with the method of halo photometry. This light curve reveals a…
PLATO as it is: a legacy mission for Galactic archaeology
A. Miglio, C. Chiappini, B. Mosser +102
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high-resolution chrono-chemo-kinematical maps of the Galaxy.…
A Distant Mirror: Solar Oscillations Observed on Neptune by the Kepler K2 Mission
P. Gaulme, J. F. Rowe, T. R. Bedding +24
Starting in December 2014, Kepler K2 observed Neptune continuously for 49 days at a 1-minute cadence. The goals consisted of studying its atmospheric dynamics (Simon et al. 2016),…
Euclid Asteroseismology and Kuiper Belt Objects
A. Gould, D. Huber, D. Stello
Euclid, which is primarily a dark-energy/cosmology mission, may have a microlensing component, consisting of perhaps four dedicated one-month campaigns aimed at the Galactic bulge.…
Asteroseismology of Exoplanet-Host Stars in the Kepler Era
Tiago L. Campante
New insights on stellar evolution and stellar interior physics are being made possible by asteroseismology, the study of stars by the observation of their natural, resonant oscilla…
WFIRST Ultra-Precise Astrometry II: Asteroseismology
A. Gould, D. Huber, M. Penny +1
WFIRST microlensing observations will return high-precision parallaxes, sigma(pi) < 0.3 microarcsec, for the roughly 1 million stars with H<14 in its 2.8 deg^2 field toward the Gal…
