Young Stars in IC 2118 - Round 2
|
IC 2118, the Witch Head Nebula (~210 parsecs), is a region of star formation located
near the supergiant star Rigel in the constellation Orion. Last year, we observed the head
of the nebula and approximately QUADRUPLED the number of young stars known here.
We propose using IRAC and MIPS to continue our investigation by observing the densest
part of the rest of the cloud. Our team proposes to use IRAC and MIPS observations to
(1) investigate star formation, (2) look for likely cluster member stars with infrared
excesses, and characterize this young star population by obtaining their colors and
therefore estimates of masses and ages, (3) study the distribution of stars, their
relationship to the ISM, and the possibilities of triggered star formation, (4) compare the
young star population, distribution, and age to other similar sites of star formation, e.g.,
IC 1396 and (5) produce a dramatic image of the interstellar medium in the region
surrounding IC 2118. Since this region is in the Orion constellation near the bright star
Rigel, it provides additional appeal to students and the general public.
