HD 715 b, a Warm Jupiter Orbiting a Massive Subgiant Discovered from a Single TESS Transit

Alexander Venner, Robert A. Wittenmyer, Andrew Vanderburg +23

Transiting Warm Jupiters orbiting bright stars are scarcely known, but a substantial number of these planets have been uncovered by the TESS mission. In this work we report the dis…

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…

Characterizing bright Scuti pulsators using TESS light curves:II. Pulsation amplitude and energy distributions

Prasad Mani, Timothy Bedding, Simon Murphy +2

Pulsations in Scuti stars exhibit a wide range of excited frequencies and amplitudes, but the underlying principles governing their amplitude distribution remain unclear. We re…

NGC 1901: A new benchmark cluster for gyrochronology in the TESS Southern continuous viewing zone

Mara Bernizzoni, Timothy R. Bedding, Prasad Mani +5

We use Gaia DR3 astrometry and TESS time-series photometry to study NGC 1901, a sparse open cluster in the TESS Southern continuous viewing zone, that has been neglected due to its…

A Highly Reflective Atmosphere on the Lava World TOI-561b Revealed by JWST/NIRSpec Phase Curve

Samuel Boucher, Lisa Dang, Alex McGinty +15

Ultra-short period (USP) rocky planets are expected to be depleted of any substantial gaseous envelope due to the intense irradiation they receive from their host star, making the…

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…
