Blue straggler stars - Open Access .click

International Astronomical Union Colloquium, 1976
SummaryA list of open clusters with blue stragglers studied for Ap characteristics is presented. In addition to previously published results new spectroscopic data are given of blue stragglers in the open cluster IC 4756 derived from ESO spectrograms taken in 1973. Preliminary conclusions concerning the status of Ap stars and blue stragglers are drawn.

Abundance patterns in unevolved A stars and in blue stragglers

AIP Conference Proceedings, 1995
On the basis of high‐resolution spectrometry and NLTE analysis we investigate abundance patterns of non‐nuclear origin in normal main‐sequence A stars and in their metal‐deficient counterparts, the Lambda Bootis stars. We try to identify and separate the effects of diffusion (gravitational settling, radiative levitation) and accretion (separation of ...

Spectroscopy of Blue Stragglers and Turno. Stars in NGC 2506 with FLAMES

2006
We present preliminary results of lithium abundances in turnoff stars in the open cluster NGC 2506. Some fifty turnoff stars and a few blue stragglers have been observed using the FLAMES facility on the VLT, during half a night from the French Guaranteed Time on this instrument.
