Descripción
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.
Investigamos la estructura fina del cúmulo abierto NGC 2516. Este es un cúmulo abierto extendido y relativamente joven que subtiende más de dos grados en el cielo, situado a unos pocos cientos de PARSECs (< 400 pc) del Sol. Recopilamos datos de Gaia DR2 (magnitud G hasta G=19, índice de color BP-RP, movimientos propios y paralaje) para más de 400 000 estrellas en una región de 6 grados de lado, y aplicamos nuestro algoritmo de membresía pyUPMASK. Los datos de GAIA para los miembros más probables se correlacionaron con fotometría UBVI. Finalmente, usamos nuestro código ASteCA para obtener los parámetros fundamentales del cúmulo.
