CSI2264: Simultaneous optical and X-ray variability in the pre-main sequence stars of NGC2264. II: Photometric variability, magnetic activity, and rotation in classIII objects and stars with transition disks
M. G. Guarcello, E. Flaccomio, G. Micela +6
Pre-main sequence stars are variable sources. In diskless stars this variability is mainly due to the rotational modulation of dark photospheric spots and active regions, as in mai…
The Gaia-ESO Survey: The inner disc, intermediate-age open cluster Pismis 18
D. Hatzidimitriou, E. V. Held, E. Tognelli +34
Pismis 18 is a moderately populated, intermediate-age open cluster located within the solar circle at a Galactocentric distance of about 7 kpc. Few open clusters have been studied…
The complex phenomena of YSOs revealed by their X-ray variability
Salvatore Sciortino, Ettore Flaccomio, Ignazio Pillitteri +1
X-ray observations of Young Stellar Objects (YSOs) have shown several complex phenomena at work.In recent years a few X-ray programs based on long, continuous and, sporadically, si…
The Gaia-ESO Survey: age spread in the star forming region NGC6530 from the HR diagram and gravity indicators
L. Prisinzano, F. Damiani, V. Kalari +33
In very young clusters, stellar age distribution is the empirical proof of the duration of star formation (SF) and of the physical mechanisms involved in the process. We derived ac…
A deep X-ray view of the Class I YSO Elias 29 with XMM-Newton and NuSTAR
I. Pillitteri, S. Sciortino, F. Reale +4
[Abridged] We investigated the X-ray characteristics of the Class I YSO Elias 29 with joint XMM-Newton and NuSTAR observations of 300 ks and 450 ks, respectively. These are the fir…
Simultaneous Kepler/K2 and XMM-Netwon observations of superflares in the Pleiades
M. G. Guarcello, G. Micela, S. Sciortino +10
Flares are powerful events ignited by a sudden release of magnetic energy. With the aim of studying flares in the 125-Myr-old stars in the Pleiades observed simultaneously in optic…
