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…
Untapped: Veloce Detects Calcium in the Atmosphere of WASP-189b
Nicholas W. Borsato, Joachim Krüger, Daniel B. Zucker +3
High-resolution transmission spectroscopy has become a powerful tool for detecting atomic and ionic species in the atmospheres of ultra-hot Jupiters. In this study, we demonstrate…
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…
The Pictoris b Hill sphere transit campaign. Paper II: Searching for the signatures of the Pictoris exoplanets through time delay analysis of the Scuti pulsations
Sebastian Zieba, Konstanze Zwintz, Matthew Kenworthy +34
The Pictoris system is the closest known stellar system with directly detected gas giant planets, an edge-on circumstellar disc, and evidence of falling sublimating bodies and…
Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS
Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33
We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…
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…
TOI-4641b: An Aligned Warm Jupiter Orbiting a Bright (V=7.5) Rapidly Rotating F-star
Allyson Bieryla, George Zhou, Juliana García-Mejía +25
We report the discovery of TOI-4641b, a warm Jupiter transiting a rapidly rotating F-type star with a stellar effective temperature of 6560 K. The planet has a radius of 0.73 $R_{J…
