X-ray rotational modulation of a supersaturated star in IC 2391
A. Marino, G. Micela, G. Peres +1
We present evidence of X-ray rotational modulation on VXR45, a young fast rotator star, member of IC 2391. It is a dG9 spectral type star whose rotational period and X-ray luminosi…
Luminosity and Mass Function of the Galactic open cluster NGC 2422
L. Prisinzano, G. Micela, S. Sciortino +1
We present UBVRI photometry of the open cluster NGC 2422 (age yr) down to a limiting magnitude . These data are used to derive the Luminosity and Mass Functi…
An XMM-Newton-based X-ray survey of pre-main sequence stellar emission in the L1551 star-forming complex
F. Favata, G. Giardino, G. Micela +2
We present a study of the X-ray sources present in the nearby L1551 star forming region, based on a deep XMM observation complemented with Chandra data for the brightest sources. A…
Time evolution of X-ray coronal activity in PMS stars; a possible relation with the evolution of accretion disks
E. Flaccomio, G. Micela, S. Sciortino
We investigate the evolution of X-ray stellar activity from the age of the youngest known star forming regions (SFR), < 1Myr, to about 100 Myr, i.e. the zero age main sequence (ZAM…
