Mass segregation and elongation of the starburst cluster Westerlund 1
Mario Gennaro, Wolfgang Brandner, Andrea Stolte +1
Massive stellar clusters are the best available laboratories to study the mass function of stars. Based on NTT/SofI near-infrared photometry, we have investigated the properties of…
A New Method for the Assessment of Age and Age-Spread of Pre-Main Sequence Stars in Young Stellar Associations of the Magellanic Clouds
Nicola Da Rio, Dimitrios A. Gouliermis, Mario Gennaro
We present a new method for the evaluation of the age and age-spread among pre-main-sequence (PMS) stars in star-forming regions in the Magellanic Clouds, accounting simultaneously…
Internal dynamics and membership of the NGC 3603 Young Cluster from microarcsecond astrometry
Boyke Rochau, Wolfgang Brandner, Andrea Stolte +5
We have analyzed two epochs of HST/WFPC2 observations of the young Galactic starburst cluster in NGC 3603 with the aim to study its internal dynamics and stellar population. Relati…
ΔY/ ΔZ from the analysis of local K dwarfs
Mario Gennaro, Pier Giorgio Prada Moroni, Scilla Degl'Innocenti
The stellar helium-to-metal enrichment ratio, ΔY/ΔZ, is a widely studied astrophysical quantity. However, its value is still not precisely constrained. This paper is focused on the…
