Raquel Salmeron The mechanism(s) responsible for generating the angular momentum transport required for star/planet formation remain poorly understood. ... In recent times it has been realised that the answer may lie in the complex interaction of gas and magnetic fields present in the flattened disc of material that surrounds the star in formation (e.g., Balbus Hawley 1998) . ...

... Denis Puy . ... More recently, Puy & Signore (1995), from this simple description, but with a more complete chemistry (primordial , HD and LiH molecules) considered the three phases of the protoclouds supposed to be initially spherical: i) a linear evolution which approximately follows the expansion, ii) a turn around epoch ( ) when the protocloud reaches its maximum value, and iii) a non-linear evolution or the collapse of the protocloud. ...

In this new series we present observations and modelling of spectral lines formed in main sequence star chromospheres (from G0 to M8). in this paper, we discuss the Hydrogen line formations in very active dMe stellar chromospheres. ... Our final model atmosphere is described in the next paper in this series. ... We found that observations are best reproduced by a chromospheric structure including a constant temperature gradient (in a log(M) scale) in the chromosphere and transition region. ...

Dwarf novae are a subclass of cataclysmic variable stars in which a late-type secondary fills its Roche lobe and transfers mass to a white dwarf primary via an accretion disc. ... Those spiral structures are very similar to the spiral shocks discovered by Sawada, Matsuda & Hachisu (1986) in 2D finite difference numerical simulations in accretion discs. In this poster, we want to compare 2D numerical simulations of accretion disc with the observations of SH2 . ...

... Anticipated Radiation Effects . ... Various radiation effects can be anticipated, based on similarities to other CMOS devices. ... Total dose radiation effects in CMOS devices can be divided into two broad classes: charge trapping and interface state generation. ... When interface states are located in a depletion region, they act as sources of dark current. Increased dark current is expected to be the dominant radiation effect in active pixel sensors, leading to increased shot noise. ...
