We present results of a population synthesis study aimed at examining the role of spin-kick alignment in producing a correlation between the spin period of the first-born neutron star and the orbital eccentricity of observed double neutron star binaries in the Galactic disk. We find spin-kick alignment to be compatible with the observed correlation, but not to alleviate the requirements for low...

This is a special issue of the Star Formation Newsletter, which brings abstracts of recent Ph.D. theses related to young stars, associated phenomena and molecular clouds. Each of the 18 abstracts in the following pages describe a major effort within its field, and we can during the next year expect to see a host of papers giving details of these exciting results. Rather than making a yearly iss...

Wiseman Physics Department, University of Michigan, Ann Arbor, MI 48109, USA Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA We extend a newly developed formal system for the description of astrophysical maps.

We review current understanding of star formation, outlining an overall theoretical framework and the observations that motivate it. A conception of star formation has emerged in which turbulence plays a dual role, both creating overdensities to initiate gravitational contraction or collapse, and countering the effects of gravity in these overdense regions. The key dynamical processes involved ...

We investigate the recent and current star formation activity of galaxies as function of distance from the cluster center in a sample of 521 SDSS clusters at z < 0.1. We characterize the recent star formation history by the strength of the 4000Å break and the strength of the Balmer absorption lines, and thus probe the star formation history over the last ∼ 2Gyr. We show that when the Brightest ...

Wide-field far-UV (FUV, 1344–1786 Å) and near-UV (NUV, 1771–2831 Å) imaging from GALEX provides a deep, comprehensive view of the young stellar populations in hundreds of nearby galaxies, shedding new light on the process of star formation (SF) in different environments, and on the interplay between dust and SF. GALEX’s FUV-NUV color is extremely sensitive to stellar populations of ages up to a...

A general treatment of disk star formation is developed from a dissipative multi-phase model, with the dominant dissipation due to cloud collisions. The Schmidt-Kennicutt law emerges naturally for star-forming disks and starbursts. We predict that there should be an inverse correlation between Tully-Fisher law and Schmidt-Kennicutt law residuals. The model is extended to include a multi-phase t...
