TL;DR: The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000 quasars, 30,000 stars, and 30, 000 serendipity targets as discussed by the authors.

Journal ArticleDOI
The Pulsar kick velocity distribution
TL;DR: In this paper, the authors analyse the sample of pulsar proper motions, taking detailed account of the selection effects of the original surveys, and find that the mean birth speed of a pulsar is 250-300 km/s.
Journal ArticleDOI
The initial-final mass relation : direct constraints at the low-mass end
Jasonjot S. Kalirai,Brad M. S. Hansen,Daniel D. Kelson,David B. Reitzel,R. Michael Rich,Harvey B. Richer +5 more
TL;DR: In this article, the authors present CFHT CFH12K photometric and Keck LRIS multi-object spectroscopic observations of 22 white dwarfs in two older open clusters, NGC 7789 and NGC 6819, and show that the observed general trend at higher masses continues down to low masses, with -->Minitial = 1.6 M? main-sequence stars forming -->Mfinal = 0.54 M? white dwarFS.
Journal ArticleDOI
Migration then assembly: formation of neptune-mass planets inside 1 au
Brad M. S. Hansen,Norm Murray +1 more
TL;DR: In this article, the observed distribution of hot Neptune/super-Earth systems is well reproduced by a model in which planet assembly occurs in situ, with no significant migration post-assembly.
