Self-regulated reionization
Ilian T. Iliev, Garrelt Mellema, Paul R. Shapiro +1
Recently, we have presented the first large-scale radiative transfer simulations of reionization. Here we present new simulations which extend the source halo mass range downward t…
R Coronae Borealis at the 2003 Light Minimum
N. Kameswara Rao, David L. Lambert, Matthew D. Shetrone
High-resolution optical spectra of R CrB obtained in 2003 March is discussed. The 2003 spectra are compared with the extensive collection of spectra from the 1995-1996 minimum. Spe…
Analysis of the dust evolution in the circumstellar disks of TTauri stars
A. Schegerer, S. Wolf, N. V. Voshchinnikov +2
We present a compositional analysis of 8-13um spectra of 32 young stellar objects (YSOs). Our sample consists of 5 intermediate-mass stars and 27 low-mass stars. While the spectra…
VLT/UVES Observations of Interstellar Molecules and Diffuse Bands in the Magellanic Clouds
D. E. Welty, S. R. Federman, R. Gredel +2
We discuss the abundances of interstellar CH, CH+, and CN in the Magellanic Clouds (MC), derived from spectra of 7 SMC and 13 LMC stars obtained (mostly) with the VLT/UVES. CH and/…
