UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
A Planet Orbiting the Star Rho Coronae Borealis
R. W. Noyes, S. Jha, S. G. Korzennik +5
We report the discovery of near-sinusoidal radial velocity variations of the G0V star rhoCrB, with period 39.6 days and amplitude 67 m/s. These variations are consistent with the e…
Radii and Distances of Cepheids, I., Method and Measurement Errors
Martin Krockenberger, Dimitar D. Sasselov, Robert W. Noyes
We develop a formulation of the Baade-Wesselink method which uses the Fourier coefficients of the observables. We derive an explicit, analytic expression to determine the mean radi…
Discovery of Diffuse X-ray Emission in 47 Tuc
Martin Krockenberger, J. Grindlay
We present the results of a search for diffuse x-ray sources in a 65 ksec ROSAT PSPC exposure of 47 Tuc. There is faint, soft emission on the NE side of the cluster at a distance o…
