Type II supernova spectral diversity I: Observations, sample characterization and spectral line evolution
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +23
We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post explosion. In this first…
VLT Spectroscopic Analysis of HH 202. Implications on dust destruction and thermal inhomogeneities
José N. Espíritu, Antonio Peimbert, Gloria Delgado-Inglada +1
We present a long-slit spectroscopic analysis of Herbig-Haro 202 and the surrounding gas of the Orion Nebula using data from the Very Large Telescope. Given the characteristics of…
Search for giant planets in M67 III: excess of hot Jupiters in dense open clusters
A. Brucalassi, L. Pasquini, R. Saglia +10
Since 2008 we used high-precision radial velocity (RV) measurements obtained with different telescopes to detect signatures of massive planets around main-sequence and evolved star…
Binary frequency of planet-host stars at wide separations: A new brown dwarf companion to a planet-host star
N. Lodieu, A. Perez-Garrido, V. J. S. Bejar +5
The aim of the project is to improve our knowledge on the multiplicity of planet-host stars at wide physical separations. We cross-matched approximately 6200 square degree area of…
Discovery of a new Y dwarf: WISE J030449.03-270508.3
D. J. Pinfield, M. Gromadzki, S. K. Leggett +21
We present a new Y dwarf, WISE J030449.03-270508.3, confirmed from a candidate sample designed to pick out low temperature objects from the WISE database. The new object is typed Y…
VISTA Variables in the Vía Láctea (VVV): Halfway Status and Results
Maren Hempel, Dante Minniti, István Dékány +89
The VISTA Variables in the Vía Láctea (VVV) survey is one of six public ESO surveys, and is now in its 4th year of observing. Although far from being complete, the VVV survey has a…
