Abstract:
We investigate the young (proto)stellar population in NGC 2023 and the
L 1630 molecular cloud bordering the H II region IC 434, using Spitzer
IRAC and MIPS archive data, JCMT SCUBA imaging and spectroscopy as
well as targeted BIMA observations of one of the Class 0 protostars,
NGC 2023 MM 1.
We study the distribution of gas, dust and young stars in this region
to see where stars are forming, whether the expansion of the H II
region has triggered star formation, and whether dense cold cores have
already formed stars.
We have performed photometry of all IRAC and MIPS images, and used
color-color diagrams to identify and classify all young stars seen
within a 22'x26' field along the boundary between IC 434 and L 1630.
Description:
The observations of NGC 2023 MM 1/MM 2 were made on Dec. 13, 1999 and
April 13, 2000 using one frequency setting in the C-array
configuration of the Berkeley-Illinois-Maryland Association (BIMA)
interferometric array.
We obtained several large scan maps (8'x8') of the NGC 2023 region
with the Submillimeter Common User Bolometer Array (SCUBA) on JCMT
during SCUBA commissioning time on four nights in December, 1997.
