TESS flares and chromospheric variability in the Pleiades, the Hyades, and Praesepe

A. Görgei, K. Vida, B. Seli +5

Magnetic activity is a result of the interaction between rotation and dynamo processes in cool stars with outer convection zones. Since open cluster members share a common age, dis…

Stellar flares with Ariel: detection prospects and impacts on exoplanet spectroscopy

K. Vida, B. Seli, B. Edwards

Stellar flares are important tracers of magnetic activity and can significantly influence the characterization of exoplanet host stars by introducing time-dependent astrophysical v…

The FU Ori outburst of PR Ori B

Carlos Contreras Pena, Zsofia Nagy, Gregory Herczeg +42

We report the discovery of a nearby FU Ori-type outburst (FUor), PR Ori B, in the L1641 cluster of the Orion star-forming region. The high-amplitude variability was first identifie…

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…

Interferometric Images of the Starspot Evolution of Andromedae

Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +21

The evolution of starspots of the giant primaries of RS CVn systems is typically detected indirectly with photometric and spectroscopic monitoring. These observations suggest slowl…
