Scientific paper
In this dissertation, I focus on the formation of low-mass stars, those stars with masses comparable to our own Sun. Mostly, my efforts center around the analysis of data from submillimeter and infrared telescopes, but I also consider an evolutionary picture of a forming star.
In Chapter 2, I present submillimeter continuum observations of 17 Class I protostars. These data were obtained with the James Clerk Maxwell Telescope's Submillimetre Common User's Bolometer Array (SCUBA) and the work has been completed with the collaboration of Yancy Shirley, Neal Evans and Jonathan Rawlings. I analyze the data and present my results in this chapter (also in Young et al. 2003. ApJS, 145, 111).
Chapter 3 is a description of Spitzer Space Telescope observations of a "starless core," Lynds 1014. L1014 was part of the validation observations for the Legacy Program, From Molecular Cores to Planet-Forming Disks (c2d), and was the first star-forming core with no IRAS detection to be observed by Spitzer. In these observations, we detected a protostar embedded within the L1014 dark cloud. Chapter 3 offers a description of the multi-wavelength continuum and spectral line observations and is also in Young et al. (2004, ApJS, 154, 396).
I present an analysis of evolutionary signatures for an evolving protostar in Chapter 4. I have considered the inside-out collapse scenario of Shu (1977) and adapt it to include a disk and first hydrostatic core, which both affect the protostar's evolution. Then, I provide observational tools that will hopefully prove useful in scrutinizing this theory of protostar formation. This work is also presented in Young & Evans (2005. ApJ, 627; astro-ph/0503456).
Finally, in Chapter 5, I report on (SCUBA) observations for 38 star-forming cores at different stages of evolution. These data were collected as a complement to the c2d program and cover some of the same areas observed by the Spitzer Space Telescope. In this chapter, I present the data, some basic analysis, and comparisons of the SCUBA data for a few sources with Spitzer observations.
