SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…
Long-term optical and near-infrared photometric evolution of SN 2019vxm, an interacting Type IIn supernova
Klára Lelkes, László Molnár, József Vinkó +12
The diversity of Type IIn supernovae is largely driven by the properties of the circumstellar material (CSM) they explode into. We examine the temporal evolution of SN 2019vxm, an…
Three fast-spinning medium-sized Hilda asteroids uncovered by TESS
Nóra Takács, Csaba Kiss, Róbert Szakáts +8
Hilda asteroids, which orbit in a 3:2 resonance with Jupiter, serve as key indicators of dynamical processes in the early solar system. Their spin rates, an important probe of thes…
Short- and long-term variations of the high mass accretion rate classical T Tauri star DR Tau
Gabriella Zsidi, Ãgnes Kóspál, Péter Ãbrahám +20
Classical T Tauri stars are newly formed, low mass stars which may display both periodic and random variations in their brightness. The interaction between the star and its circums…
