Angular momentum transport in astrophysics and in the lab

ASTROPHYSICS Variable stars in nearby galaxies ?

The light curves of Cepheids and other variable stars in Field A of IC 1613, obtained with a CCD and no filter (Wh photometry), have been analyzed. It is possible to separate first overtone from fundamental mode population I Cepheids taking into account the pulsation amplitude, the shape of the light curve and the period. The expected separation is verified in the period–luminosity PL diagram. ...

ASTROPHYSICS Properties of He - rich stars

We present a study of helium rich atmospheres in the interval He/H 0.1–1.0 as derived from fully consistent model computations for effective temperature (from 15000K up to 32000K) and surface gravity (log g=3.5 and 4.0). Also the basic diagnostic tools are re-examined, particularly, broad-band UBV and intermediate photometric systems, hydrogen line profiles, continuum fluxes and helium equivale...

Quark matter and the astrophysics of neutron stars

Some of the means through which the possible presence of nearly deconfined quarks in neutron stars can be detected by astrophysical observations of neutron stars from their birth to old age are highlighted.
