Resumen:
G 126.1--0.8--14 is a molecular shell located in the Orion arm, at a
distance of about 1 kpc. The HII region Sh2-187 is located over the
border of this shell. Previous works show that Sh2-187 is a small
(? 9') and young (? 2 × 10^5 yr) ionized region that
shows signs of recent star formation in its surroundings. On the other
hand, based on color criteria, we have found several infrared (MSX and
IRAS) sources candidates of being young stellar objects (YSO) or
ultracompact HII regions (UCHII) located projected onto the shell. In
this work we present an analysis of the possible origin of G
126.1--0.8--14 and its possible roll in the formation of new stars.
