Spectroscopy of High-Redshift Supernovae from the ESSENCE Project: The First Two Years

T. Matheson, S. Blondin, R. J. Foley +28

We present the results of spectroscopic observations of targets discovered during the first two years of the ESSENCE project. The goal of ESSENCE is to use a sample of ~200 Type Ia…

Testing blend scenarios for extrasolar transiting planet candidates. II. -- OGLE-TR-56

Guillermo Torres, Maciej Konacki, Dimitar D. Sasselov +2

We re-examine the photometric and spectroscopic evidence available for the star OGLE-TR-56, recently discovered to harbor a giant planet presenting transits and orbiting with a per…

Hubble Space Telescope and Ground-Based Observations of SN 1993J and SN 1998S: CNO Processing in the Progenitors

Claes Fransson, Peter M. Challis, Roger A. Chevalier +13

Ground-based and Hubble Space Telescope observations are presented for SN 1993J and SN 1998S. SN 1998S shows strong, relatively narrow circumstellar emission lines of N III-V and C…

Testing blend scenarios for extrasolar transiting planet candidates. I. -- OGLE-TR-33: a false positive

Guillermo Torres, Maciej Konacki, Dimitar D. Sasselov +2

We report high-resolution spectroscopic follow-up observations of the faint transiting planet candidate OGLE-TR-33 (V = 14.7), located in the direction of the Galactic center. Smal…

A transiting extrasolar giant planet around the star OGLE-TR-113

Maciej Konacki, Guillermo Torres, Dimitar D. Sasselov +6

We report the independent discovery of a new extrasolar transiting planet around OGLE-TR-113, a candidate star from the Optical Gravitational Lensing Experiment. Small radial-veloc…
