Gas and Dust Associated with the Strange, Isolated, Star BP Piscium
B. Zuckerman, C. Melis, Inseok Song +15
We have carried out a multiwavelength observational campaign demonstrating some of the remarkable properties of the infrared-bright variable star BP Psc. Surrounded by a compact du…
Metal Absorption Systems in Spectra of Pairs of QSOs
David Tytler, Mark Gleed, Carl Melis +6
We present the first large sample of absorption systems in paired QSOs consisting of 691 absorption systems in the spectra of 310 QSOs including 170 pairings. All these absorption…
The Chemical Composition of an Extrasolar Minor Planet
B. Zuckerman, D. Koester, C. Melis +2
We report the relative abundances of 17 elements in the atmosphere of the white dwarf star GD 362, material that, very probably, was contained previously in a large asteroid or ast…
The H I opacity of the intergalactic medium at redshifts 1.6 < z < 3.2
David Kirkman, David Tytler, Nao Suzuki +8
We use high quality echelle spectra of 24 QSOs to provide a calibrated measurement of the total amount of Lyman-alpha forest absorption (DA) over the redshift range 2.2 < z < 3.2.…
