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…

Radar-Chart Analysis of Star-Formation Quenching Stages Across Circular Velocity Curve Classes in Nearby CALIFA Galaxies

Veselina Kalinova, Dario Colombo

We analyze the circular velocity curves of 215 non-active galaxies from the Calar Alto Legacy Integral Field spectroscopy Area survey. Using radar-chart analysis, we compare two cl…

Shape model and dynamical state of the asteroid (300) Geraldina: Implications for its possible ancient origin

G. Apostolovska, N. Todorovic, E. Vchkova Bebekovska +3

In this study, we present a comprehensive photometric and physical characterisation of the main-belt asteroid (300) Geraldina. Our analysis includes determining its sidereal rotati…

A distant brown dwarf coplanar to a warm Jupiter and a hot super-Earth

Matías I. Jones, Luca Naponiello, Trifon Trifonov +21

In transiting planetary systems, in which planetary sizes are accurately determined from transit observations, the presence of transit-timing variations (TTVs), especially when com…

Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions

D. Akl, S. Antier, H. Koehn +105

Most long gamma-ray bursts (GRBs) exhibit afterglows broadly consistent with external forward-shock emission, typically described by smooth broken power-law decays in the multiband…

Long-period magnetic activity in the K dwarf GJ 1137 and a new super-Earth on a 9-day orbit

Denitza Stoeva, Atanas K. Stefanov, Stefan Y. Stefanov +12

Aims: We investigate long-term radial velocity (RV) variability in the K-dwarf star GJ 1137 (HD 93083, HIP52521), a known Saturn-mass exoplanet host, and assess the role of stellar…
