RR Lyrae stars: Kinematics, orbits and z-distribution
Gisela Maintz, Klaas S. de Boer
RR Lyrae stars in the Milky Way are good tracers to study the kinematic behaviour and spatial distribution of older stellar populations. A recently established well documented samp…
Kinematics of RHB stars to trace the structure of the galaxy
T. A. Kaempf, K. S. de Boer, M. Altmann
Red horizontal-branch (RHB) stars have been selected from the HIPPARCOS catalogue to investigate their kinematics and spatial distribution. HIPPARCOS parallaxes, literature radial…
The contribution of halo red giant mass loss to the high-velocity gas falling onto the Milky Way disk
Klaas S. de Boer
The origin of gas falling from the halo toward the disk of the Milky Way is still largely unclear. Here the amount of gas shed by the (older) halo red giants is estimated. The dist…
Intermediate scale structure of the interstellar medium towards NGC 6231 in Sco OB1 with FUSE
O. Marggraf, H. Bluhm, K. S. de Boer
The FUSE far-ultraviolet interstellar spectra toward seven targets in NGC 6231 show that the molecules H_2, HD, and CO as well as various atomic species are distributed in several…
Studying the populations of our Galaxy using the kinematics of sdB stars
M. Altmann, H. Edelmann, K. S. de Boer
We have analysed the kinematics of a sample of 114 hot subdwarf stars, for 2/3 of which we present new proper motions, spectroscopic and photometric data. The vast majority of the…
Interstellar H_2 in M 33 detected with FUSE
Hartmut Bluhm, Klaas S. de Boer, Ole Marggraf +2
FUSE spectra of the four brightest H II regions in M 33 show absorption by interstellar gas in the Galaxy and in M 33. On three lines of sight molecular hydrogen in M 33 is detecte…
