Rings Around Non-Spherical Worlds: Sub-mm Dust Retention Around Triaxial Small Bodies in the Solar System
Zs. Regaly, V. Frohlich, Cs. Kalup +1
We investigated the millennial-scale evolution of narrow innermost rings composed of pebble-sized to sub-millimeter particles around the four known ring-bearing small bodies Chiron…
Beyond solar metallicity: How enhanced solid content in disks re-shape low-mass planet torques
Zs. Regaly, A. Nemeth
The migration of low-mass planets is tightly controlled by the torques exerted by both gas and solids in their natal disks. While canonical models assume a solar solid-to-gas mass…
Limits of Standard Tidal Models at Quaoar: Matching Weywot's Orbit, Missing the Spin
Zsolt Regaly, Viktoria Frohlich, Csaba Kiss
Weywot, Quaoar's small satellite, follows a nearly circular orbit at a distance of 12.9 times Quaoar's diameter and coexists with a compact ring system. Nevertheless, Quaoar's flat…
SN 2023ixf in M101: physical parameters from bolometric light curve modeling
J. Vinko, Zs. R. Bodola, A. Godeny +25
We present new photometric observations of the core-collapse supernova SN 2023ixf occurred in M101, taken with the RC80 and BRC80 robotic telescopes in Hungary. The initial nickel…
Fine-Tuned Supernova or Failed Explosion? Decoding the Origins of the G3425 Binary
Zsolt Regaly, Viktoria Frohlich, Jozsef Vinko
A binary system (G3425) consisting of a massive unseen component and a red giant star on a nearly circular orbit was recently discovered. The formation of such a system is puzzling…
Grand Theft Moons. Formation of habitable moons around giant planets
Zoltan Dencs, Vera Dobos, Zsolt Regaly
Of the few thousand discovered exoplanets, a significant number orbit in the habitable zone of their star. Many of them are gas giants lacking a rocky surface and solid water reser…
