On the origin of the short-period Blue Straggler Stars in Collinder 261: a binary evolution approach
M. Echeveste, M. J. Rain, G. Carraro +3
Building on the recent publication of a fresh catalog of blue straggler stars in Galactic open clusters using Gaia DR3, we conduct a study focusing on the blue straggler stars with…
Sky Quality Meter and satellite correlation for the night cloud cover analysis at astronomical sites
S. Cavazzani, S. Ortolani, A. Bertolo +5
The analysis of the night cloud cover is very important for astronomical observation in real time, considering a typical observation time of about 15 minutes, and to have a statist…
A study of the blue straggler population of the old open cluster Collinder 261
M. J. Rain, G. Carraro, J. A. Ahumada +4
Blue Stragglers are stars located in an unexpected region of the color-magnitude diagram of a stellar population, as they appear bluer and more luminous than the stars in the turno…
Ecology of Blue Straggler Stars
H. M. J. Boffin, G. Carraro, G. Beccari
The existence of blue straggler stars (BSS), which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution, as such star…
Introduction to the Theory of Stellar Evolution
G. Beccari, G. Carraro
In this chapter we briefly review the basics of the theory of stellar evolution.
Stellar populations in the surrounding field of the LMC clusters NGC 2154 and NGC 1898
E. Chiosi, G. Baume, G. Carraro +2
In this paper we present a study and comparison of the star formation rates (SFR) in the fields around NGC 1898 and NGC 2154, two intermediate-age star clusters located in very dif…
A photometric study of the young open cluster NGC 1220
S. Ortolani, G. Carraro, S. Covino +2
We present UBV CCD observations obtained in the field of the northern open cluster NGC 1220, for which little information is available. We provide also BV CCD photometry of a field…
An optical and near IR study of the old open cluster NGC 2141
G. Carraro, S. Hassan, S. Ortolani +1
We report on CCD optical (B and V passbands) and near IR (J and K bands) observations in the region of the old open cluster NGC 2141. By combining the two sets of photometry (500 s…
Dwarf Elliptical Galaxies: Structure, Star Formation, and Color-Magnitude Diagrams
G. Carraro, C. Chiosi, L. Girardi +1
The aim of this paper is to cast light on the formation and evolution of elliptical galaxies by means of N-body/hydro-dynamical simulations that include star formation, feed-back a…
The elusive old population of the dwarf spheroidal galaxy Leo I
Enrico V. Held, Ivo Saviane, Yazan Momany +1
We report the discovery of a significant old population in the dwarf spheroidal (dSph) galaxy Leo I as a result of a wide-area search with the ESO New Technology Telescope. Studies…
On the galactic disc age-metallicity relation
G. Carraro, Y. K. Ng, L. Portinari
A comparison is made between the age-metallicity relation obtained from four different types of studies: F and G stars in the Solar Neighbourhood, analysis of open clusters, galact…
