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…
Uncovering a 260 pc wide, 35 Myr old filamentary relic of star formation
Giacomo Beccari, Henri M. J. Boffin, Tereza Jerabkova
Several recent studies have shown that the Vela OB2 region hosts a complex constellation of sub-populations with ages in the range 10 to 50 Myr. Such populations might represent th…
A stellar relic filament in the Orion star forming region
Tereza Jerabkova, Henri M. J. Boffin, Giacomo Beccari +1
We report the discovery of the oldest stellar substructure in the Orion star forming region (OSFR), the Orion relic filament. The relic filament is physically associated with the O…
When the tale comes true: multiple populations and wide binaries in the Orion Nebula Cluster
Tereza Jerabkova, Giacomo Beccari, Henri M. J. Boffin +5
The high-quality OmegaCAM photometry of the 3x3 deg around the Orion Nebula Cluster (ONC) in r, and i filters by Beccari et al.(2017) revealed three well-separated pre-main sequenc…
Discovery of a double Blue Straggler sequence in M15: new insight into the core-collapse process
Giacomo Beccari, Francesco R. Ferraro, Emanuele Dalessandro +8
In this paper we report on the discovery of a double blue straggler star (BSS) sequence in the core of the core-collapsed cluster M15 (NGC 7078). We performed a detailed photometri…
Photometric determination of the mass accretion rates of pre-main sequence stars. VI. The case of LH 95 in the Large Magellanic Cloud
Katia Biazzo, Giacomo Beccari, Guido De Marchi +1
We report on the accretion properties of low-mass stars in the LH95 association within the Large Magellanic Cloud (LMC). Using non-contemporaneous wide-band and narrow-band photome…
