Constraining the orbit of the retrograde planet in the Octantis system

Alan Cefali Signor, Alexandre C. M. Correia, Maria Helena Moreira Morais +4

The Octantis system is composed of a compact stellar binary and a retrograde S-type planet orbiting near the edge of stability. Here, we investigate the dynamically viable arch…

Dynamical analysis of the 5:1 mean-motion resonance of the HD 202206 system

Yingyi Cao, Man Hoi Lee, Sabine Reffert +2

The HD 202206 system, which features two substellar companions with a 5:1 period ratio around a solar-type star, offers a rare opportunity to study high-order mean-motion resonance…

Resonant Chains and the Convergent Migration of Planets in Protoplanetary Disks

Ka Ho Wong, Man Hoi Lee

An increasing number of compact planetary systems with multiple planets in a resonant chain have been detected. The resonant chain must be maintained by convergent migration of the…

A new third planet and the dynamical architecture of the HD33142 planetary system

Trifon Trifonov, Anna Wollbold, Martin Kürster +24

Based on recently-taken and archival HARPS, FEROS and HIRES radial velocities (RVs), we present evidence for a new planet orbiting the first ascent red giant star HD33142 (with an…

Precise radial velocities of giant stars XV. Mysterious nearly periodic radial velocity variations in the eccentric binary Cygni

Paul Heeren, Sabine Reffert, Trifon Trifonov +10

Using the Hamilton Echelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars over more than 12 years, leadi…

The CARMENES search for exoplanets around M dwarfs. Characterization of the nearby ultra-compact multiplanetary system YZ Ceti

S. Stock, J. Kemmer, S. Reffert +38

The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three planets. The orbital period of each planet is the subject of discussion in the literature due to s…
