WELCOME! to the web site of Phil Armitage at the University
of Colorado in Boulder, where I am an
Associate Professor in the Department of
Astrophysical and Planetary Sciences
and a Fellow at JILA.
My research focuses on the formation
and early evolution of extrasolar planetary systems, and the astrophysics
of black holes. I am on sabbatical during the 2009-2010 academic year, but
my normal teaching includes a range of primarily upper division undergraduate and graduate classes.

A complete
list of my publications via ADS.
My graduate level textbook
on planet formation is available through Cambridge University Press. The textbook is a greatly expanded version of my
Lecture notes on the formation and early
evolution of planetary systems, which I plan to continue updating as a freely
available reference.

RESEARCH INTERESTS

I am currently working with University of Colorado graduate students
Jared Workman and Anna Hughes, and with postdoctoral fellow Kris Beckwith.
Past members of my group include former student Dimitri Veras (now a postdoc
at the University of Florida), and postdoc Ken Rice (now on the faculty at
the University of Edinburgh). Other collaborators include former Colorado
postdocs Richard Alexander (Leiden), Sean Raymond (Bordeaux), Daniel Proga (UNLV), Jorge Cuadra (MPA) and
Elena Rossi (Racah Institute).

My research in theoretical and computational astrophysics focuses on two
main areas. I am broadly interested in
planet
formation and protoplanetary disk evolution, including studies of
angular momentum transport in protoplanetary disks, the formation of
giant and terrestrial planets, and the early evolution of extrasolar
planetary systems. I also work more generally in the field of
accretion
disk theory, where the goals are to elucidate the basic physics of
accretion and to make predictions for observable phenomena around young
stars, compact objects, and black holes.

Apart from the above, my interests include hiking, running, triathlon and photography.
I maintain a separate web site of landscape photography,
mostly from the National Parks and wilderness areas of North America.
Finally, there's the usual list of web links.

Last word from Fred Brooks' The
Mythical Man-Month
"The
programmer builds from pure thought-stuff: concepts and very flexible representations
thereof. Because the medium is tractable, we expect few difficulties in implementation;
hence our pervasive optimism. Because our ideas are faulty, we have bugs; hence our
optimism is unjustified."
