HE 1015-2050: Discovery of a Hydrogen-deficient carbon star at high galactic latitude
HE 1015-2050 Hydrogen-deficient carbon star
2011/1/10
Medium resolution spectral analysis of candidate Faint High Latitude Carbon (FHLC) stars from Hamburg/ESO survey has given us the potential to discover objects of rare types. Two primary spectral char...

2010/11/12
Measurement of redshifted 21-cm emission from neutral hydrogen promises to be the most e ective method for studying the reionisation history of hydrogen and,indirectly, the rst galaxies. These studie...
Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
ISM lines and bands − ISM molecules
2010/11/15
We establish correlations between equivalent widths of eight diffuse interstel-lar bands (DIBs), and examine their correlations with atomic hydrogen, molec-ular hydrogen, and EB−V . The DIBs are...
