Antonova Física, Astronomía y Matemáticas low mass Stars surveys proper motions We used the VISTA Variables en V ́ıa L ́actea (VVV) survey to search for large proper motion (PM) objects in the zone of avoidance in the Milky Way bulge and southern Galactic disk. This s urvey is multi-epoch and already spans a period of more than four years, giving us an excellent opportunit y for proper motion and parallax studies. We found around 1700 PM objects with PM > 30 mas yr − 1 . The majority of them are early and mid M-dwarfs. There are also few later spectral type objects, as well as numerous new K- and G-dwarfs. 75 of the stars have PM > 300 mas − 1 and 189 stars have PM > 200 mas − 1 . There are only 42 previously known stars in the VVV area with proper motion PM > 200 mas − 1 . We also found three dM+WD binaries and new members of the immediate solar vicinity of 25 pc. We generated a catalog which will be a complementary to the existing catalogs outside this zone. 2015 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57150514013 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.46 |
