Fine structure of the main sequence of NGC 2516 scrutinized with Gaia and ASteCA
The fine structure of the open cluster NGC 2516 is investigated. This is an extended and relatively young open cluster subtending over two degrees in the sky, situated at just a few hundred PARSECs (< 400 pc) from the Sun. We collected Gaia DR2 data (G magnitude down to G=19, BP-RP color index, p...

| Sumario: | The fine structure of the open cluster NGC 2516 is investigated. This is an extended and relatively young open cluster subtending over two degrees in the sky, situated at just a few hundred PARSECs (< 400 pc) from the Sun. We collected Gaia DR2 data (G magnitude down to G=19, BP-RP color index, proper motions, and parallaxes) for more than 400 000 stars in a region of 6 degrees on a side, and applied our membership algorithm pyUPMASK. GAIA data for the most probable members was cross-matched with available UBVI data. Finally, we run our ASteCA code to obtain the fundamental cluster parameters. |
