The near-IR luminosity-metallicity relationship for dwarf irregular galaxies
Ivo Saviane, R. Riegerbauer, E. V. Held +6
We briefly describe our on-going investigation of the near-IR luminosity-metallicity relationship for dwarf irregular galaxies in nearby groups of galaxies. The motivations of the…
Resonant and Secular Families in the Kuiper Belt
E. I. Chiang, J. R. Lovering, R. L. Millis +3
We review ongoing efforts to identify occupants of mean-motion resonances (MMRs) and collisional families in the Edgeworth-Kuiper belt. Direct integrations of trajectories of Kuipe…
An XMM and Chandra view of massive clusters of galaxies to z=1
L. R. Jones, B. J. Maughan, H. Ebeling +7
The X-ray properties of a sample of high redshift (z>0.6), massive clusters observed with XMM-Newton and Chandra are described, including two exceptional systems. One, at z=0.89, h…
Stellar Winds of Hot Massive Stars Nearby and Beyond the Local Group
Fabio Bresolin, Rolf-Peter Kudritzki
Photospheric radiation momentum is efficiently transferred by absorption through metal lines to the gaseous matter in the atmospheres of massive stars, sustaining strong winds and…
Properties of Circum(sub)stellar Accretion Disks
Michael C. Liu, Alan T. Tokunaga, Joan Najita
We have completed a systematic survey for disks around young brown dwarfs and very low mass stars. By choosing a well-defined sample and by obtaining sensitive thermal IR observati…
Disks around Young Brown Dwarfs
Michael C. Liu
We present some results from a systematic survey for disks around spectroscopically identified young brown dwarfs and very low mass stars. We find that ~75% of our sample show intr…
