9 Jul 2003 | Journal: | Astron.Astrophys. 407 (2003) L63-L66 | Subject: | astro-ph | Abstract: | 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 luminosity make it a supersaturated star. Our X-ray observation, made with EPIC/PN on XMM-Newton, covers about two photometric rotational periods. The detection of rotational modulation implies the presence of structural inhomogeneities. Possible interpretations are presented and discussed. | Source: | arXiv, astro-ph/0307170 | Services: | Forum | Review | PDF | Favorites |
