Hot Subdwarfs in Binaries as the Source of the Far-UV Excess in Elliptical Galaxies
Philipp Podsiadlowski, Zhanwen Han, Anthony E. Lynas-Gray +1
The excess of far-ultraviolet (far-UV) radiation in elliptical galaxies has remained one of their most enduring puzzles. In contrast, the origin of old blue stars in the Milky Way,…
Binary Stars as the Source of the Far-UV Excess in Elliptical Galaxies
Zhanwen Han, Philipp Podsiadlowski, Anthony E. Lynas-Gray
The discovery of an excess of light in the far-ultraviolet (UV) spectrum in elliptical galaxies was a major surprise in 1969. While it is now clear that this UV excess is caused by…
The separation of the stars in the binary nucleus of the planetary nebula Abell 35
A. A. Gatti, J. E. Drew, R. D. Oudmaijer +2
Using the Planetary Camera on board the Hubble Space Telescope we have measured the projected separation of the binary components in the nucleus of the planetary nebula Abell 35 to…
