III/49 White Dwarf Catalogue (Luyten 1970)
White Dwarfs
Luyten W.J.
<Univ. of Minnesota, Minneapolis (1970)>
ADC_Keywords: Stars, white dwarf;
Description:
The catalogue includes all probale white dwarf and degenerate stars
found in the Proper Motion and Faint Blue Star Surveys conducted by
W.J. Luyten.
As a guideline for the inclusion of stars into this catalogue, the
author has used stars which present minimal values of
H = m + 5 + 5 log µ (µ is the proper motion in arcsec/yr)
which show the minimal H values according to the color class:
b 13.5 f 15.5 g-k 17.7
a 14.4 g 17.0 k 18.3
Note that the columns containing the proper motion (µ and θ),
as well as the notes, are not included in the present version.
