Deep FORS1 observations of the double Main Sequence of omega Centauri
A. Sollima, F. R. Ferraro, M. Bellazzini +3
We present the results of a deep photometric survey performed with FORS1@VLT aimed at investigating the complex Main Sequence structure of the stellar system omega Centauri. We con…
The pure non-collisional Blue Straggler population in the giant stellar system omega Centauri
F. R. Ferraro, A. Sollima, R. T. Rood +3
We have used high spatial resolution data from the Hubble Space Telescope and wide-field ground-based observations to search for blue straggler stars (BSS) over the entire radial e…
Stellar and gaseous abundances in M82
L. Origlia, P. Ranalli, A. Comastri +1
The near infrared (IR) absorption spectra of starburst galaxies show several atomic and molecular lines from red supergiants which can be used to infer reliable stellar abundances.…
Starbursts in active galaxy nuclei: observational constraints from IR stellar absorption lines
E. Oliva, L. Origlia, R. Maiolino +1
High quality infrared spectra of active galaxies including the stellar absorption features of Si at 1.59 um, CO(6,3) at 1.62 um, and CO(2,0) at 2.29 um are used to measure the stel…
