Stellar lifetime and ultraviolet properties of the old metal-rich Galactic open cluster NGC6791: a pathway to understand the UV upturn of elliptical galaxies
Stellar lifetime ultraviolet properties old metal-rich Galactic cluster NGC6791 UV upturn elliptical galaxies
2012/2/23
The evolutionary properties of the old metal-rich Galactic open cluster NGC6791 are assessed, based on deep UB photometry and 2Mass JK data. For 4739 stars in the cluster, bolometric luminosity and ef...
Identification of the Lithium Depletion Boundary and Age of the Southern Open Cluster Blanco 1
Identification the Lithium Depletion Boundary
2011/1/13
We present results from a spectroscopic study of the very low mass members of the Southern open cluster Blanco 1 using the Gemini-N telescope. We obtained intermediate resolution (R~4400) GMOS spectra...

In this paper, we study the characteristics and physical properties of the young open cluster Pleiades (NGC 1432; M45; Melotte 22; Seven Sisters) using Near Infra Red, JHK pass bands. Our results have...
Stellar and substellar mass function of the young open cluster candidates Alessi 5 and beta Monocerotis
Stellar substellar mass young open cluster candidates beta Monocerotis
2010/11/10
Although the stellar and substellar populations have been studied in various young and old open clusters, additional studies in clusters in the age range from 5 to 100Myr is crucial (e.g. to give more...
Debris discs in the 27 Myr old open cluster IC4665
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
We present Spitzer IRAC and MIPS 24um imaging of members of the 27+/-5Myr old open cluster IC 4665. Models for the assembly of terrestrial planets through planetesimal collisions and mergers predict e...
WIYN Open Cluster Study. XXXVIII. Stellar Radial Velocities in the Young Open Cluster M35 (NGC 2168)
open clusters and associations individual (NGC 2168) - (stars:) binaries spectroscopic
2010/3/8
We present 5201 radial-velocity measurements of 1144 stars, as part of an ongoing study of the young (150 Myr) open cluster M35 (NGC 2168). We have observed M35 since 1997, using the Hydra Multi-Objec...

2010/3/8
Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theory of stellar evoluti...
