UBVRIz Light Curves of 51 Type II Supernovae
Lluís Galbany, Mario Hamuy, Mark M. Phillips +34
We present a compilation of UBV RIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986 to 2003: the Cerro Tololo Supernova Sur…
HATS-15 b and HATS-16 b: Two massive planets transiting old G dwarf stars
S. Ciceri, L. Mancini, T. Henning +28
We report the discovery of HATS-15 b and HATS-16 b, two massive transiting extrasolar planets orbiting evolved ( Gyr) main-sequence stars. The planet HATS-15 b, which is h…
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
HATS-17b: A Transiting Compact Warm Jupiter in a 16.3 Days Circular Orbit
R. Brahm, A. Jordán, G. Á. Bakos +19
We report the discovery of HATS-17b, the first transiting warm Jupiter of the HATSouth network. HATS-17b transits its bright (V=12.4) G-type (M=1.131 0.030 M$_{\odo…
Measuring nickel masses in Type Ia supernovae using cobalt emission in nebular phase spectra
Michael J. Childress, D. John Hillier, Ivo Seitenzahl +34
The light curves of Type Ia supernovae (SNe Ia) are powered by the radioactive decay of Ni to Co at early times, and the decay of Co to Fe from ~60 days…
