Abstract

The globular cluster NGC 4590 has been observed at Haute Provence Observatory (photographic photometry, 80-cm reflector, F/6) and at the European Southern Observatory (image-tube, 152-cm reflector, F/15).
  • A sequence of red magnitudes, m r (λ eff ≅6400 Å) has been established around the cluster. It comprises 28 stars with magnitudes between 11.66 and 16.50.

  • Five new variable stars were discovered in a one square degree field, centered on the cluster.

  • Four other variable stars (No. 39, 40, 41, and 42) were discovered in the cluster.
