The magnetic field of the B3V star 16 Pegasi
H. F. Henrichs, C. Neiner, R. S. Schnerr +8
The Slowly Pulsating B3V star 16 Pegasi was discovered by Hubrig (2006) to be magnetic, based on low-resolution spectropolarimetric observations with FORS1 at the VLT. We have conf…
Star-forming galaxies in SDSS: signs of metallicity evolution
M. A. Lara-Lopez, J. Cepa, A. Bongiovanni +5
Evolution of galaxies through cosmic time has been widely studied at high redshift, but there are a few studies in this field at lower redshifts. However, low-redshifts studies wil…
The XMM-Newton long look of NGC 1365: uncovering of the obscured X-ray source
G. Risaliti, M. Salvati, M. Elvis +10
We present an analysis of the extreme obscuration variability observed during an XMM-Newton 5-days continuous monitoring of the AGN in NGC 1365. The source was in a reflection-domi…
Parameters of Herbig Ae/Be and Vega-type stars
Benjamin Montesinos, Carlos Eiroa, Alcione Mora +1
This work presents the determination of the effective temperature, gravity, metallicity, mass, luminosity and age of 27 young early-type stars, most of them in the age range 1-10 M…
XMM-Newton observation of MACHO 104.20906.960: a dwarf nova candidate with a 2 h period
A. A. Nucita, S. Carpano, F. De Paolis +3
The binaries known as cataclysmic variables are particular binary systems in which the primary star (a white dwarf) accretes material from a secondary via Roche-lobe mechanism. Usu…
CAIXA: a Catalogue of AGN In the XMM-Newton Archive I. Spectral analysis
Stefano Bianchi, Matteo Guainazzi, Giorgio Matt +2
We present CAIXA, a Catalogue of AGN In the XMM-Newton Archive. It consists of all the radio-quiet X-ray unobscured ( cm) Active Galactic Nuclei…
