The impact of envelope binding energies on the merger rate density of binary compact objects

Cecilia Sgalletta, Guglielmo Costa, Giuliano Iorio +8

The common envelope (CE) phase plays a key role in the formation of binary compact object systems. Its final outcome strongly depends on the envelope binding energy, but this quant…

A homogeneous view of asymptotic giant branch carbon stars as seen by Gaia

Alessio Liberatori, Despina Hatzidimitriou, Konstantinos Antoniadis +12

Carbon stars on the asymptotic giant branch are major contributors to galactic dust enrichment, with gas mass-loss rates up to 1e-4 Msun/yr. We present a homogeneous spectral energ…

Enhanced Mass Loss of Very Massive Stars: Impact on the Evolution, Binary Processes, and Remnant Mass Spectrum

Kendall G. Shepherd, Guglielmo Costa, Cristiano Ugolini +7

Very massive stars (VMS) play a fundamental role in astrophysics due to their winds and supernovae (SN), and their role as massive black hole (BH) progenitors. However, their origi…

Strikingly high fraction of fast rotators in Magellanic Cloud star clusters

Greta Ettorre, Alessandro Mazzi, Leo Girardi +14

There has been growing evidence that the rich star clusters in the Magellanic Clouds contain significant fractions of rapidly rotating stars. In this work, we aim to constrain thes…

The Local Ultraviolet to Infrared Treasury I. Survey Overview of the Broadband Imaging

Karoline M. Gilbert, Yumi Choi, Martha L. Boyer +21

The Local Ultraviolet to Infrared Treasury (LUVIT) is a Hubble Space Telescope program that combines newly acquired data in the near ultraviolet (NUV), optical, and near infrared (…
