The EXTraS Project: Exploring the X-ray transient and variable sky
A. De Luca, R. Salvaterra, A. Belfiore +29
Temporal variability in flux and spectral shape is ubiquitous in the X-ray sky and carries crucial information about the nature and emission physics of the sources. The EPIC instru…
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…
Multi-wavelength observations of 3FGL J2039.6-5618: a candidate redback millisecond pulsar
D. Salvetti, R. P. Mignani, A. De Luca +8
We present multi-wavelength observations of the unassociated gamma-ray source 3FGL J2039.6-5618 detected by the Fermi Large Area Telescope. The source gamma-ray properties suggest…
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…
