Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
HST/COS Spectra of the Wind Lines of VFTS 102 and 285
Katherine Shepard, Douglas R. Gies, Kathryn V. Lester +5
Rapid rotation in massive stars imposes a latitudinal variation in the mass loss from radiatively driven winds that can lead to enhanced mass loss at the poles (with little angular…
Tidally Excited Oscillations in Heartbeat Binary Stars: Pulsation Phases and Mode Identification
Zhao Guo, Avi Shporer, Kelly Hambleton +1
Tidal forces in eccentric binary stars known as heartbeat stars excite detectable oscillations that shed light on the processes of tidal synchronization and circularization. We exa…
The first view of Scuti and Doradus stars with the TESS mission
V. Antoci, M. S. Cunha, D. M. Bowman +63
We present the first asteroseismic results for Scuti and Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilise the 2-min cadence TESS data for a sample…
A Mass-accreting Gamma Doradus Pulsator with a Synchronized Core in Kepler Eclipsing Binary KIC 7385478
Zhao Guo, Gang Li
The short-period (P d), Algol-type eclipsing binary KIC 7385478 consists of an F-type primary star () and an evolved K-type secondary ($M_2…
KIC 4142768: An Evolved Gamma Doradus/Delta Scuti Hybrid Pulsating Eclipsing Binary with Tidally Excited Oscillations
Zhao Guo, Jim Fuller, Avi Shporer +5
We present the characterization of KIC 4142768, an eclipsing binary with two evolved A-type stars in an eccentric orbit with a period of 14 days. We measure the fundamental paramet…
Visual Orbits of Spectroscopic Binaries with the CHARA Array. II. The eclipsing binary HD 185912
Kathryn V. Lester, Douglas R. Gies, Gail H. Schaefer +8
We present the visual orbit of the double-lined eclipsing binary, HD 185912, from long baseline interferometry with the CHARA Array. We also obtain echelle spectra from the Apache…
Asteroseismology of massive stars with the TESS mission: the runaway Beta Cep pulsator PHL 346 = HN Aqr
Gerald Handler, Andrzej Pigulski, Jadwiga Daszyńska-Daszkiewicz +21
We report an analysis of the first known Beta Cep pulsator observed by the TESS mission, the runaway star PHL 346 = HN Aqr. The star, previously known as a singly-periodic pulsator…
