Liller 1

Liller 1 , or Liller I , is a globular Amas of our Galaxie located in the Constellation of the Scorpion. It is known to shelter an atypical object, a Sursauteur X called Rapid Burster . It is besides following the discovery of this object that research was made to determine of which object this sursautor formed part. Liller 1 was found in 1977 by William Liller. Although carrying a number, Liller 1 is actually the only globular cluster named in the honor of W. Liller.

Physical characteristics

Liller 1 is practically located in the galactic Plan, with only 6 degrees of the galactic Center. Its distance, estimated by Photometry using the Space telescope Hubble, locates it at a distance close to that of the galactic center, to which it is consequently very close.

It is a very red globular cluster (i.e. with a weak Indice of color) and with high Métallicité. It forms part, with NGC 6553, NGC 6440 and NGC 6528 of the globular cluster to the highest metallicity of our galaxy, and has of this fact been the subject of several studies. This reveals that these globular clusters were formed very early in the history of our Galaxy, and knew a fast enrichment out of metals because of stellar Nucléosynthèse.
