Spectroscopic study of solar twins and analogues
Juliet Datson, Chris Flynn, Laura Portinari
Context. Many large stellar surveys have been and are still being carried out, providing huge amounts of data, for which stellar physical parameters will be derived. Solar twins an…
VLT/X-shooter spectroscopy of the afterglow of the Swift GRB 130606A: Chemical abundances and reionisation at
O. E. Hartoog, D. Malesani, J. P. U. Fynbo +28
The reionisation of the Universe is thought to have ended around z~6, as inferred from spectroscopy of distant bright background sources, such as quasars (QSO) and gamma-ray burst…
Towards stellar effective temperatures and diameters at one per cent accuracy for future surveys
L. Casagrande, L. Portinari, I. S. Glass +8
The apparent size of stars is a crucial benchmark for fundamental stellar properties such as effective temperatures, radii and surface gravities. While interferometric measurements…
Solar analogues and Solar twins in the HARPS archive
Juliet Datson, Chris Flynn, Laura Portinari
We present 63 Solar analogues and twins for which high S/N archival data are available for the HARPS high resolution spectrograph at the ESO 3.6m telescope. We perform a differenti…
New solar twins and the metallicity and temperature scales of the Geneva Copenhagen Survey
Juliet Datson, Chris Flynn, Laura Portinari
We search for "solar twins" in the Geneva-Copenhagen Survey (GCS) using high resolution optical spectroscopy. We initially select Sun-like stars from the GCS by absolute magnitude,…
