EXTraS discovery of an X-ray superflare from an L dwarf
A. De Luca, B. Stelzer, A. J. Burgasser +13
We present the first detection of an X-ray flare from an ultracool dwarf of spectral class L. The event was identified in the EXTraS database of XMM-Newton variable sources, and it…
Results from DROXO IV. EXTraS discovery of an X-ray flare from the Class I protostar candidate ISO-Oph 85
Daniele Pizzocaro, Beate Stelzer, Roberta Paladini +15
X-ray emission from Young Stellar Objects (YSOs) is crucial to understand star formation. A very limited amount of X-ray results is available for the protostellar (ClassI) phase. A…
Follow-up observations of X-ray emitting hot subdwarf star: the He-rich sdO BD +37° 1977
N. La Palombara, P. Esposito, S. Mereghetti +2
We report on the results of the first XMM-Newton satellite observation of the luminous and helium-rich O-type subdwarf BD +37° 1977 carried out in April 2014. X-ray emission is det…
