Discovery of lambda Boo stars in open clusters
C. Saffe, J. Alacoria, A. Alejo +7
The origin of lambda Boo stars is currently unknown. After several efforts by many authors, no bona fide lambda Boo stars have been confirmed as members of open clusters. Their det…
Searching for lambda Boo stars in binary systems
J. Alacoria, C. Saffe, A. Collado +7
Our goal is to find new candidate lambda Boo stars that belong to binary systems. A detailed abundance determination of some candidates could confirm their true lambda Boo nature,…
Disentangling the origin of chemical differences using GHOST
C. Saffe, P. Miquelarena, J. Alacoria +8
Aims. We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD 138202 + CD-30 12303. For the first time, we suggest ho…
GIARPS@TNG GIANO-B & HARPS-N together for a wider wavelength range spectroscopy
R. Claudi, S. Benatti, I. Carleo +36
Since 2012, thanks to the installation of the high resolution echelle spectrograph in the optical range HARPS-N, the Italian telescope TNG (La Palma) became one of the key faciliti…
VLBA determination of the distance to nearby star-forming regions I. The distance to T Tauri with 0.4% accuracy
Laurent Loinard, Rosa M. Torres, Amy J. Mioduszewski +5
In this article, we present the results of a series of twelve 3.6-cm radio continuum observations of T Tau Sb, one of the companions of the famous young stellar object T Tauri. The…
