The Stellar Observations Network Group (SONG) -- A Legacy Archive of Stellar Time-Domain Spectroscopy

M. N. Lund, F. Grundahl, M. S. Fredslund +41

The Stellar Observations Network Group (SONG) network has operated for more than a decade, providing long-baseline, high-cadence spectroscopic observations of bright stars and the…

Enhanced magnetic activity in rapidly rotating binary stars

Jie Yu, Charlotte Gehan, Saskia Hekker +12

Stellar activity is fundamental to stellar evolution and the formation and habitability of exoplanets. The interaction between convective motions and rotation in cool stars results…

A catalog of binary stars from phase modulation in the first four years of TESS Mission photometry

Shishir Dholakia, Simon J. Murphy, Chelsea X. Huang +2

We present a catalog of binary companions to Scuti stars, detected through phase modulations of their pulsations in TESS data. Pulsation timing has provided orbits for hundreds…

New Evidence of Binarity in Young α-Rich Turn-off and Subgiant Stars: Fast Rotation and Strong Magnetic Activity

Jie Yu, Luca Casagrande, Ioana Ciucă +3

Young α-rich (YAR) stars within the old Galactic thick disk exhibit a dual characteristic of relative youth determined with asteroseismology and abundance enhancement in α elements…

Identifying 850 delta Scuti pulsators in a narrow Gaia colour range with TESS 10-minute full-frame images

Amelie K. Read, Timothy R. Bedding, Prasad Mani +7

We use TESS 10-minute Full Frame Images (Sectors 27-55) to study a sample of 1708 stars within 500 pc of the Sun that lie in a narrow colour range in the centre of the delta Scuti…

TESS Cycle 2 observations of roAp stars with 2-min cadence data

D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46

We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
