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…
Activity and rotation of the X-ray emitting Kepler stars
Daniele Pizzocaro, Beate Stelzer, Ennio Poretti +6
The relation between magnetic activity and rotation in late-type stars provides fundamental information on stellar dynamos and angular momentum evolution. Rotation/activity studies…
Detailed X-ray spectroscopy of the magnetar 1E 2259+586
D. Pizzocaro, A. Tiengo, S. Mereghetti +7
Magnetic field geometry is expected to play a fundamental role in magnetar activity. The discovery of a phase-variable absorption feature in the X-ray spectrum of SGR 0418+5729, in…
