Jan Eberhardt, Trifon Trifonov, Martin Kürster +15
We present an independent Doppler validation and dynamical orbital analysis of the two-planet system HD 107148, which was recently announced in Rosenthal et al. (2021). Our detaile…
Accretion variability from minutes to decade timescales in the classical T Tauri star CR Cha
G. Zsidi, C. F. Manara, Á. Kóspál +6
Classical T Tauri stars are surrounded by a circumstellar disk from which they are accreting material. This process is essential in the formation of Sun-like stars. Although often…
A pair of warm giant planets near the 2:1 mean motion resonance around the K-dwarf star TOI-2202
Trifon Trifonov, Rafael Brahm, Nestor Espinoza +37
TOI-2202 b is a transiting warm Jovian-mass planet with an orbital period of P=11.91 days identified from the Full Frame Images data of five different sectors of the TESS mission.…
TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet
Ares Osborn, David J. Armstrong, Bryson Cale +125
We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…
Highly structured inner planetary system debris around the intermediate age Sun-like star TYC 8830 410 1
Carl Melis, Johan Olofsson, Inseok Song +4
We present detailed characterization of the extremely dusty main sequence star TYC 8830 410 1. This system hosts inner planetary system dust (Tdust~300 K) with a fractional infrare…
Dipper-like variability of the Gaia alerted young star V555 Ori
Zsófia Nagy, Elza Szegedi-Elek, Péter Ábrahám +26
