Star FormationColorInterstellar GasStellar EvolutionWe present evidence for a dependence on luminosity of the neutral hydrogen mass to luminosity ratio in a large sample of irregular galaxies of moderate or low surface brightness. This is not valid for active bright irregulars of the Markaryan class...

A close correlation is found between the 1.4 GHz radio luminosity and the integrated far infrared (FIR) luminosity of Wolf-Rayet galaxies. This correlation is essentially the same as that for spiral galaxies. Objects with intense star formation predominate among the Wolf-Rayet galaxies with excess ...

based on the observed association between GRB 030329 and supernova SN 2003dh. The neutrino spectral flux distributions can test for possible delays between the supernova and the gamma-ray burst events down to much shorter timescales than what can be resolved with photons. As an illustrative exa...
As the pressure and, hence, the energy generation increase with the mass, the MLR is a consequence of the pressure and temperature gradient inside the stars, and its validity extends beyond Eddington's special star models to all stars with a chemically homogeneous interior composition.With the ...
