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…
Magnetic activity in cool stars: manifestations and relevance to exoplanets
E. Işık, A. Valio, A. Strugarek +10
Understanding stellar magnetic activity is central to exoplanet science in two ways: it sets the dynamic astrospheric boundary condition governing planetary space environments, and…
Sub-second cadence structure of optical flares on AD Leo
B. Schmercz, B. Seli, K. Vida +4
Stellar flares are sudden brightenings caused by magnetic reconnection and are frequently observed on late-type stars. High-cadence photometry of flares provides valuable insights…
Long-term X-ray variability of the multiple-planet host L 98-59: Hints of an activity cycle
I. Pillitteri, S. Bellotti, S. Benatti +7
High-energy irradiation in X-rays and UV (XUV) can transform the planetary atmospheres through photoevaporation and photochemistry. This is more crucial for M stars, whose habitabl…
Magnetic activity on the young Sun: a case study of EK Draconis
A. Görgei, L. Kriskovics, K. Vida +8
Context. Young, solar analogue stars provide key insights into the early stages of stellar evolution, particularly in terms of magnetic activity and rotation. Their rapid rotation,…
Four decades of photometry of XX Trianguli, `the most spotted star' in the sky
Zs. Kővári, K. G. Strassmeier, K. Oláh +3
Over the past 40 years the brightness variations of XX Tri, a single line RS CVn type binary system with a synchronized K-giant primary, has exceeded one magnitude in the V band. A…
Radio emission from flaring stars and brown dwarfs
K. Perger, B. Seli, K. Vida
Aims. With the aim to reveal the effects of the magnetic field to the multi-band activity of dwarf stars, we search for associated radio emission for an extensive list of 14 915 br…
Stellar flare morphology with TESS across the main sequence
Bálint Seli, Krisztián Vida, Katalin Oláh +5
Stellar flares are abundant in space photometric light curves. As they are now available in large enough numbers, the statistical study of their overall temporal morphology is time…
Magnetic activity under tidal influences in the 2+2~hierarchical quadruple system V815 Herculis
Zs. Kővári, K. G. Strassmeier, L. Kriskovics +5
Tidal forces in close binaries and multiple systems that contain magnetically active component are supposed to influence the operation of magnetic dynamo. Through synchronization t…
Searching for stellar CMEs in the Praesepe and Pleiades clusters
K. Vida, B. Seli, R. M. Roettenbacher +4
On the Sun, the energetic, erupting phenomena of flares and coronal mass ejections (CMEs) often occur together. While space-based photometry has revealed frequent white-light flare…
Detecting coronal mass ejections with machine learning methods
K. Vida, B. Seli, T. Szklenár +3
Flares on the Sun are often associated with ejected plasma: these events are known as coronal mass ejections (CMEs). These events, although are studied in detail on the Sun, have o…
Characteristics of flares on giant stars
Katalin Oláh, Bálint Seli, Zsolt Kővári +2
Although late-type dwarfs and giant stars are substantially different, their flares are thought to originate in similar physical processes and differ only by a scale factor in the…
