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.
