Proper Motions of Dwarf Spheroidal Galaxies from Hubble Space Telescope Imaging. V: Final Measurement for Fornax
Slawomir Piatek, Carlton Pryor, Paul Bristow +5
The measured proper motion of Fornax, expressed in the equatorial coordinate system, is mas century. This proper motion is a weighted…
Transiting extrasolar planetary candidates in the Galactic bulge
Kailash C. Sahu, Stefano Casertano, Howard E. Bond +13
More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and…
The `666' collaboration on OGLE transits: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry
Frederic Pont, Claire Moutou, Michael Gillon +14
Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. He…
VLT-UVES abundance analysis of four giants in NGC 6553
A. Alves-Brito, B. Barbuy, M. Zoccali +9
Metal-rich globular clusters trace the formation of bulges. Abundance ratios in the metal-rich globular clusters such as NGC 6553 can constrain the formation timescale of the Galac…
Oxygen abundances in the Galactic Bulge: evidence for fast chemical enrichment
M. Zoccali, A. Lecureur, B. Barbuy +6
AIMS: We spectroscopically characterize the Galactic Bulge to infer its star formation timescale, compared to the other Galactic components, through the chemical signature on its i…
Lightcurves of Type Ia Supernovae from Near the Time of Explosion
Arti Garg, Christopher W. Stubbs, Peter Challis +18
We present a set of 11 type Ia supernova (SN Ia) lightcurves with dense, pre-maximum sampling. These supernovae (SNe), in galaxies behind the Large Magellanic Cloud (LMC), were dis…
