Phoenix Dwarf Galaxy Stellar Kinematics

EAS Publications Series, 2011
The Phoenix dwarf galaxy is the nearest and most typical representative of the class of the so-called transition dwarf galaxies (from spheroidal to irregular). We present here precise velocity measurements obtained from high-resolution spectroscopy of more than one hundred member stars, allowing us to study the stellar kinematics and estimate the ...

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.

Stellar Kinematics from Hipparcos Proper Motions

International Astronomical Union Colloquium, 2000
AbstractFrom Hipparcos proper motions, we have analyzed the local kinematics of the Milky Way from the young 0-B5 stars, classical Cepheids, and the late-type K-M giants. Comparing the derived results, the kinematical discrepancies between each subset of stars have been analyzed, and the possible reasons for the kinematical differences have been ...

UCAC4: Stellar kinematics with vector spherical functions

Astronomische Nachrichten, 2013
AbstractWe present a method of kinematic analysis of proper motions by vector spherical functions, and the results of its application to astrometric data. The sets of vector spherical functions which are orthonormal on a full sphere as well as on a latitude zone are constructed.

The relation between molecular clouds and stellar kinematics

Astrophysics and Space Science, 1986
The relation between molecular clouds, star clusters, and the stellar component of the galactic disk is investigated. According to Elmegreen (1985) bound stellar systems, e.g., open star clusters, can be formed from molecular cloud of mass ~ 104 M ⊙. A close encounter with a giant molecular cloud or massive black hole disrupts such stellar systems and ...
