Abstract

New observations in the VI bands along with archival data from the 2MASS and WISE surveys have been used to generate a catalogue of young stellar objects (YSOs) covering an area of about 6{deg}x6{deg} in the Auriga region centred at l~173{deg} and b~1.5{deg}. The nature of the identified YSOs and their spatial distribution are used to study the star formation in the region. The distribution of YSOs along with that of the ionized and molecular gas reveals two ring-like structures stretching over an area of a few degrees each in extent. We name these structures as Auriga Bubbles 1 and 2. The centre of the Bubbles appears to be above the Galactic mid-plane. The majority of Class I YSOs are associated with the Bubbles, whereas the relatively older population, i.e. Class II objects are rather randomly distributed. Using the minimum spanning tree analysis, we found 26 probable subclusters having five or more members. The subclusters are between ~0.5 and ~3pc in size and are somewhat elongated. The star formation efficiency in most of the subcluster region varies between 5 per cent and 20 per cent indicating that the subclusters could be bound regions. The radii of these subclusters also support it.
