Abstract:

 

The  poorly  studied Berkeley  8 (Be 8) open cluster  is analyzed from CCD  U BV RI    photometric data taken with  the  0.90 m telescope  at the  Sierra  Nevada  Observatory. The  Z  =   +0.008   PARSEC isochrone  gave us a reddening of E(B-V)  = 0.69  ± 0.03, a distance of 3410  ± 300   pc, and  an  age of 2.8  ± 0.2 Gyr.   Its  median  Gaia  DR2  distance, d  = 3676  ± 810 pc, is in   good agreement with  our photometric distances, 3410-3620 pc within  the  uncertainties. The   kinematic parameters of five likely members of Be 8 with  the  circular orbits, ecc  = [0.23,    0.30] , reflect  the  properties of the  Galactic thin  disc,  which  is also  consistent  with    what  is expected of its  metal  content  ([M/H]   = -0.27).   Be 8 with  R  >  9 kpc (co-rotation   gap  at 9 kpc)  may  have  been  originating from a different galactic  radius  or different star   formation region.
