The ultracool dwarf DENIS-P J104814.7-395606. Chromospheres and coronae at the low-mass end of the main-sequence
B. Stelzer, J. Alcala, K. Biazzo +8
We have obtained an XMM-Newton observation and a broad-band spectrum from the ultraviolet to the near infrared with X-Shooter for one of the nearest M9 dwarfs, DENIS-P J1048-3956 (…
Large-scale young Gould Belt stars across Orion
K. Biazzo, J. M. Alcalá, M. F. Sterzik +3
We report first results on the large-scale distribution of the ROSAT All-Sky Survey (RASS) X-ray sources in a 5000 deg^2 field centered on Orion. Our final aim is to study the prop…
Magnetic activity and differential rotation in the very young star KIC 8429280
A. Frasca, H. -E. Fröhlich, A. Bonanno +3
We present a spectroscopic/photometric analysis of the rapid rotator KIC8429280, discovered by ourselves as a very young star and observed by the Kepler mission. We use spectroscop…
Elemental abundances of low-mass stars in the young clusters 25 Ori and lambda Ori
K. Biazzo, S. Randich, F. Palla +1
Aims. We aim to derive the chemical pattern of the young clusters 25 Orionis and lambda Orionis through homogeneous and accurate measurements of elemental abundances. Methods. We p…
