Halo Luminosity Function From Photometric Calibration of the Revised NLTT
Andrew Gould, Juna A. Kollmeier, Julio Chaname +1
We calibrate the photographic photometry of the revised New Luyten Two-Tenths catalog (rNLTT) by matching 3448 rNLTT stars to the Sloan Digital Sky Survey (SDSS). The correction is…
Spectral Classification Beyond M
S. K. Leggett, F. Allard, A. J. Burgasser +3
Significant populations of field L and T dwarfs are now known, and we anticipate the discovery of even cooler dwarfs by Spitzer and ground-based infrared surveys. However, as the n…
The Dearth of Massive, Helium-Rich White Dwarfs in Young Open Star Clusters
Jasonjot Singh Kalirai, Harvey B. Richer, Brad M. S. Hansen +2
Spectra have been obtained of 21 white dwarfs (WDs) in the direction of the young, rich open star cluster NGC 2099. This represents an appreciable fraction (>30%) of the cluster's…
The Initial-Final Mass Relationship: Spectroscopy of White Dwarfs in NGC 2099 (M37)
Jasonjot Singh Kalirai, Harvey B. Richer, David Reitzel +5
We present new observations of very faint white dwarfs (WDs) in the rich open star cluster NGC 2099 (M37). Following deep, wide field imaging of the cluster using CFHT, we have now…
