A high-resolution K-band spectral atlas of massive stars

V. M. Kalari, W. D. Vacca

A high-resolution (45000), high signal-to-noise (100) K-band spectral atlas of massive stars is presented. It includes 81 stars consisting of known optical standards, span…

No country for old stars -Spectroscopic confirmation of the first intermediate-age RR Lyrae in the open cluster Trumpler 5

Valentina D'Orazi, Cecilia Mateu, Giuliano Iorio +13

RR Lyrae stars are widely considered tracers of ancient (greater than 10 Gyr), metal-poor stellar populations. However, recent kinematic and photometric studies suggest the existen…

A Path to an All-Sky Survey with Roman

Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93

A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…

A search for Be stars in multiple systems within the solar neighborhood

V. M. Kalari, R. Salinas, C. Saez-Carvajal +9

Be stars are widely considered to be the product of binary interaction. However, whether all Be stars are formed via binary interaction is unclear, and detailed estimates of the mu…

The Gaia-ESO Survey: Projected Rotational Velocities of B stars in the Carina Nebula

W. Santos, S. Daflon, J. V. Sales Silva +19

The Carina Nebula is an active star-forming region with several open clusters rich in massive OB stars, thus making it an optimal target for studying stellar properties such as rot…
