eFEDS catalogue of variable X-ray sources
The 140 square degree Final Equatorial-Depth Survey (eFEDS) field, observed with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) aboard the... -
Search for flares and CMEs in SDSS data
This work aims to detect and classify stellar flares and potential stellar coronal mass ejection (CME) signatures in optical spectra provided by the Sloan Digital Sky Survey... -
M dwarfs rotation-activity relations and flares
Using light curves obtained by the K2 mission, we study the relation between stellar rotation and magnetic activity with a special focus on stellar flares. Our sample comprises... -
M45, M44 and M67 flare stars
The presence and strength of a stellar magnetic field and activity is rooted in a star's fundamental parameters such as mass and age. Can flares serve as an accurate stellar... -
Stellar X-ray flares from the 2XMM catalog
We present a uniform, large-scale survey of X-ray flare emission, based on the XMM-Newton Serendipitous Source Catalogue and its associated data products. Our survey comprises... -
LHS1070 photometry and spectroscopy
LHS 1070 is a nearby multiple system of low mass stars. It is an important source of information for probing the low mass end of the main sequence, down to the hydrogen-burning... -
Variable stars in a VLT/VIMOS field in Carina
We have searched for variable stars in deep V-band images of a field towards the Galactic plane in Carina. The images were taken with VIMOS instrument at ESO VLT during 4... -
UBV(RI)c photometry of active stars. X.
As part of an extensive program focused on the global properties and evolution of active stars, high-precision UBV(RI)c and UBV photometry of 18 selected stars is presented.... -
UBV(RI)c photometry of active stars. IX
As a part of an extensive program focused on the global properties and evolution of active stars, high-precision UBV(RI)c and UBV photometry of 31 selected stars is presented.... -
Optical flares on EV Lac in 1967-1977
We report on a large sample of homogeneous photoelectric data obtained by monitoring the red dwarf flare star EV Lac. The data were collected in 10 years (1967-77) at Catania... -
X-ray flare of CF Tuc (=HD 5303)
Solar abundance fits to the quiescent spectra 1-3 and 20-35 were made with a two-component thermal plasma (model 1a) whereas sub-solar abundance fits to the quiescent spectra... -
Gershberg Flare Star Catalogue
This catalog groups the flare stars as presented in the IAU Colloquium 15 (combined Colloquium of Commisions 27 and 42) held at Bamberg 31-Aug to 03-Sep 1971 entitled "New... -
Tonantzintla Pleiades Flare Stars
The original catalog lists the flare stars discovered by different astronomical observatories over an area slightly larger than 20 square degrees in the Pleiades regions...
