Structure and kinematics of edge-on galaxy discs - IV. The kinematics of the stellar discs [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2005
The stellar disc kinematics in a sample of fifteen intermediate- to late-type edge-on spiral galaxies are studied using a dynamical modeling technique. The sample covers a substantial range in maximum rotation velocity and deprojected face-on surface brightness and contains seven spirals with either a boxy- or peanut-shaped bulge.

Structure and Kinematics of the Stellar System

1988
For the quantitative description of the distribution of the stars on the sphere (galactic coordinates l, b) and by apparent magnitude, one deals with either the star numbers \( A\left( {m|l,b} \right)\Delta m \) = number of stars in the interval of apparent magnitude \( m - \frac{1} {2}\Delta m \ldots m + \frac{1} {2}\Delta m, \) which are to be found ...

Stellar Kinematics in Star-Forming Regions

International Astronomical Union Colloquium, 1984
High-precision radial-velocity studies of three young, star-forming regions - λ Orionis, NGC 2264 and Taurus-Auriga - are under way; study of the Orion cluster (with L. Marschall, in conjunction with the Yale proper-motion study) is beginning this winter.
