A Deep Precursor-Dip-Main Superoutburst Sequence in VW Hydri Observed with TESS: High-Cadence Constraints on the Thermal-Tidal Instability Model
Bisi Bernard Ogunwale, Shara Michael, Avi Shporer +2
We present 120s cadence TESS observations of three superoutbursts of the SU UMa-type dwarf nova VW Hydri. Two events (SO2 in Sectors 87+88 and SO3 in Sector 93) exhibit a pronounce…
Characterization of two new transiting sub-Neptunes and a terrestrial planet around M-dwarf hosts
E. Poultourtzidis, G. Lacedelli, E. Pallé +49
We report the confirmation of three transiting exoplanets orbiting TOI-1243 (LSPM~J0902+7138), TOI-4529 (G~2--21), and TOI-5388 (Wolf~346) that were initially detected by TESS thro…
On the Presence of Angular-Velocity Offsets in Disk Galaxies
Tomer Zimmerman, Lev Tal-Or, Roy Gomel
The well-known discrepancy in galactic rotation curves refers to the mismatch between observed rotational velocities and the velocities predicted by baryonic matter. In this study…
The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES
Daisy A. Turner, Yoshi Nike Emilia Eschen, Felipe Murgas +60
Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since th…
A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093
J. Sanz-Forcada, E. González-Ãlvarez, M. R. Zapatero Osorio +33
Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…
An updated catalog of HIRES/Keck radial velocity measurements. Including Ca II H&K measurements
Jerusalem T. Teklu, Volker Perdelwitz, R. Paul Butler +4
The first HIRES/Keck precision radial velocity (RV) catalog was released in 2017; it was followed by a second release in 2019, which incorporated corrections for small but signific…
