Diego Mardones

I was a graduate student in Astronomy at Harvard University until January 1998. My thesis work was on "Signatures of Infall in Regions of Low Mass Star Formation" under the guidance of Dr. Phil Myers.

We obtained most of the data I used in my thesis using the IRAM 30m telescope in Spain, the Haystack 37m telescope in Massachusetts, and the SEST 15m telescope in La Silla, Chile.

You can ftp each thesis chapter with the following links, the postcript files are meant to be printed on USA standard letter sized paper. All tables and figures are embedded in the text.

"Spatially Extended Motions Around Nearby Young Stellar Objects"
This is half of my thesis, it includes Appendix A with the scan maps that didn't make it into the main text.

"Radiative Transfer Models of Cores with Inward Motions"
We use a MonteCarlo spherically symmetric radiative transfer code to explore the observed line profiles from clouds with different radial profiles of inward speed, density, and kinetic temperature.

Yes, here you will find the conclusions.

Appendix B is a contribution to the Maryland conference on "Star Formation Near and Far", October 1996. Wilner, Mardones, and Myers, "Interferometric Imaging of dense Gas Tracers in the Protostellar Candidate L1527," in AIP CP 393, page 109.
Appendix C has many of the standard equations to determine column densities etc from mm-wavelength molecular lines.
Appendix D talks about the antenna radiation pattern and the observable temperature scale from a single dish radio telescope.
