Title: Star formation and Massive Stars in the Dwarf Starburst Galaxy NGC 4214
Abstract:
NGC 4214 is a nearby dwarf galaxy with multiple regions of intense
star formation spanning a range of ages. We propose near infrared
spectroscopic measurements of six major star complexes using the
Infrared Multi-Object Spectrometer (IRMOS). These observations build
upon the recent results of Rigby and Rieke (2004) that demonstrate the
ability of H and K band diagnostic lines to probe the hard UV spectral
energy distribution and reveal the massive star population. With its
low dust content and range of evolutionary states across its star
formation complexes, NGC 4214 is an ideal galaxy for a differential
study to distinguish between the competing hypotheses that there exists
a deficit of high mass stars or they are so deeply embedded in dusty
regions that their near-infrared lines are suppressed.
