Young Stellar Object Candidates in IC 417

Listed in NASA Data Portal

IC 417 is in the Galactic Plane, and likely part of the Aur OB2 association; it is ~2 kpc away.

Description

Stock 8 is one of the densest cluster constituents; off of it to the East, there is a 'Nebulous Stream' (NS) that is dramatic in the infrared (IR). We have assembled a list of literature-identified young stellar objects (YSOs), new candidate YSOs from the NS, and new candidate YSOs from IR excesses.

We vetted this list via inspection of the images, spectral energy distributions (SEDs), and color-color/color-magnitude diagrams. We placed the 710 surviving YSOs and candidate YSOs in ranked bins, nearly two-thirds of which have more than 20 points defining their SEDs. The lowest-ranked bins include stars that are confused, or likely carbon stars.

There are 503 in the higher-ranked bins; half are SED Class III, and ~40% are SED Class II.
