Asteroseismology and interferometry of the F7V spectroscopic binary Draconis A in the TESS CVZ
Jonatan Rudrasingam, Mikkel N. Lund, Frank Grundahl +26
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…
Diameters and Temperatures VII: High-angular resolution measurements of Solar-type stars with the CHARA Array
Tabetha S. Boyajian, Ashley A. Elliott, Emelly D. Tiburcio +8
We present interferometric measurements of angular diameters for 27 nearby solar-type stars obtained with the Precision Astronomical Visible Observations (PAVO) beam combiner at th…
CHARA Interferometry and TESS Asteroseismology of the Core-Helium Burning Red Giant Cyg
Arnab Chowhan, Timothy R. Bedding, Daniel Huber +5
We present a detailed study of the secondary red clump star, Cyg, by combining long-baseline visible interferometry using the PAVO beam combiner at the CHARA Array with high-pr…
Halo Photometry and Asteroseismology for 98 of the Brightest Stars Observed by TESS
Jonatan Rudrasingam, Timothy R. Bedding, Benjamin J. S. Pope +4
The Transiting Exoplanet Survey Satellite (TESS) mission has facilitated studies of asteroseismology, eclipsing binaries, and transits in many stars. However, the brightest stars 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…
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…
Benchmarking Substellar Evolutionary Models Using New Age Estimates for HD 4747 B and HD 19467 B
Charlotte M. Wood, Tabetha Boyajian, Kaspar von Braun +5
Constraining substellar evolutionary models (SSEMs) is particularly difficult due to a degeneracy between the mass, age, and luminosity of a brown dwarf. In cases where a brown dwa…
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…
Testing stellar evolution models with the retired A star HD 185351
Jakob G. Hjørringgaard, Victor Silva Aguirre, Tim R. White +5
The physical parameters of the retired A star HD 185351 were analysed in great detail by Johnson et al. (2014) using interferometry, spectroscopy and asteroseismology. Results from…
Hot super-Earths stripped by their host stars
M. S. Lundkvist, H. Kjeldsen, S. Albrecht +26
Simulations predict that hot super-Earth sized exoplanets can have their envelopes stripped by photo-evaporation, which would present itself as a lack of these exoplanets. However,…
Optical Interferometry of early-type stars with PAVO@CHARA. I. Fundamental stellar properties
V. Maestro, X. Che, D. Huber +8
We present interferometric observations of 7 main-sequence and 3 giant stars with spectral types from B2 to F6 using the PAVO beam combiner at the CHARA array. We have directly det…
Properties of oscillation modes in subgiant stars observed by Kepler
O. Benomar, T. R. Bedding, B. Mosser +7
Mixed modes seen in evolved stars carry information on their deeper layers that can place stringent constraints on their physics and on their global properties (mass, age, etc...).…
Masses of subgiant stars from asteroseismology using the coupling strengths of mixed modes
O. Benomar, T. R. Bedding, D. Stello +3
Since few decades, asteroseismology, the study of stellar oscillations, enables us to probe the interiors of stars with great precision. It allows stringent tests of stellar models…
Oscillation mode linewidths of main-sequence and subgiant stars observed by Kepler
T. Appourchaux, O. Benomar, M. Gruberbauer +20
Solar-like oscillations have been observed by {\it Kepler} and CoRoT in several solar-type stars. We study the variations of stellar p-mode linewidth as a function of effective tem…
