On the pressure equilibrium and timescales in the scale free convection theory
Stefano Pasetto, Cesare Chiosi, Mark Cropper +2
Convection is one of the fundamental energy transport processes in physics and astrophysics, and its description is central to allstellar models. In the context of stellar astrophy…
Theory of stellar convection II: first stellar models
S. Pasetto, C. Chiosi, E. Chiosi +2
We present here the first stellar models on the Hertzsprung-Russell diagram (HRD), in which convection is treated according to the novel scale-free convection theory (SFC theory) b…
Exploring an Alternative Channel of Evolution Towards SNa Ia Explosion
E. Chiosi, C. Chiosi, P. Trevisan +2
In this paper we explore the possibility that isolated CO-WDs with mass smaller than the Chandrasekhar limit may undergo nuclear runaway and SNa explosion, triggered by the energy…
Multiwavelength search for counterparts of supersoft X-ray sources in M31
E. Chiosi, M. Orio, F. Bernardini +2
We searched optical/UV/IR counterparts of seven supersoft X-ray sources (SSS) in M31 in the Hubble Space Telescope (HST) "Panchromatic Hubble Andromeda Treasury" (PHAT) archival im…
Thomson Scattering and Collisional Ionization in the X-rays Grating Spectra of the Recurrent Nova U Scorpii
M. Orio, E. Behar, J. Gallagher +3
We present a Chandra observation of the recurrent nova U Scorpii, done with the HRC-S detector and the LETG grating on day 18 after the observed visual maximum of 2010, and compare…
Pre-main sequence stars in the stellar association N11 in the Large Magellanic Cloud
Antonella Vallenari, Emanuela Chiosi, Rosanna Sordo
Magellanic Clouds are of extreme importance to the study of the star formation process in low metallicity environments. In this paper we report on the discovery of pre-main sequenc…
