Abstract

As part of its commissioning process the Near-Infrared Camera and Multiobject Spectrometer (NICMOS) obtained images of the infrared source NGC 2264 IRS, also known as Allen's source, in three colors. In addition to the completely overexposed image of IRS there are six point objects, never previously observed, at projected separations of 2″.6 to 4″.9 from IRS. These sources are interpreted as near solar mass, pre-main-sequence stars that may be the result of triggered star formation. Regardless of the star formation method, it appears certain that this group of stars is a coeval formation of various mass stars. This makes it a very valuable data set for the study of pre-main-sequence evolution.
