Abstract:
Massive star-forming regions are thought to be the most common birth
environments in the Galaxy and the only birth places of very massive
stars. Their presence in the stellar cluster alters the conditions
within the cluster impacting at the same time the evolution of other
cluster members. In principle, copious amounts of ultraviolet
radiation produced by massive stars can remove material from outer
parts of the protoplanetary disks around low- and intermediate-mass
stars in the process of external photoevaporation, effectively
reducing the planet-formation capabilities of those disks. Here, we
present deep VLT/MUSE observations of low-mass stars in Trumpler 14,
one of the most massive, young, and compact clusters in the Carina
Nebula Complex. We provide spectral and stellar properties of 717
sources and based on the distribution of stellar ages derive the
cluster age of ∼1Myr. The majority of the stars in our sample have
masses ≤1M☉, what makes our spectroscopic catalogue the most
deep to date in term of masses, and proves that detailed
investigations of low-mass stars are possible in the massive but
distant regions. Spectroscopic studies of low-mass members of the
whole Carina Nebula Complex are missing. Our work provides an
important step forward towards filling this gap and set the stage for
follow-up investigation of accretion properties in Trumpler 14.
Description:
Catalog of stellar properties of Trumpler 14 sources based on the
VLT/MUSE observations. Sample is divided into the clean catalog
(table1.dat) and the uncertain sample due to the high background
variation (tabled1.dat).
