TOI-2525 b and c: A pair of massive warm giant planets with a strong transit timing variations revealed by TESS
Trifon Trifonov, Rafael Brahm, Andres Jordan +44
TOI-2525 is a K-type star with an estimated mass of M = 0.849 M and radius of R = 0.785 R observed by the TESS mission in 22…
Dynamical architecture of the HD 107148 system
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…
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.…
A Numerical Method for Determining the Elements of Circumbinary Orbits and Its Application to Circumbinary Planets and the Satellites of Pluto-Charon
Jason Man Yin Woo, Man Hoi Lee
Planets and satellites orbiting a binary system exist in the solar system and extrasolar planetary systems. Their orbits can be significantly different from Keplerian orbits, if th…
Two Jovian planets around the giant star HD202696. A growing population of packed massive planetary pairs around massive stars?
Trifon Trifonov, Stephan Stock, Thomas Henning +6
We present evidence for a new two-planet system around the giant star HD202696 (= HIP105056, BD+26 4118). The discovery is based on public HIRES radial velocity measurements taken…
A candidate super-Earth planet orbiting near the snow line of Barnard's star
I. Ribas, M. Tuomi, A. Reiners +60
At a distance of 1.8 parsecs, Barnard's star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object. It is the closest single star to the Sun, second…
