A few links related to young stars, rotation, ...
Galleries (pretty pictures) of nebulae;
note that not all of the nebulae listed on these pages are
necessarily star-forming regions.
Star formation in general
Herbig-Haro objects, or HH objects, are (generally speaking)
knots of stuff ejected from very young stars. The
thing that I think makes them particularly cool is that sometimes
these knots are found a long way away from the star
that ejected them. There is a movie I've seen that shows some
of these things actually moving, but unfortunately,
I can't find it on the web.
Here are some of the other links I could find.
Young stars are variable, as you might guess from the name of one of the
prototype young stars, T Tauri.
The stars I study in detail are those with big star spots, like sunspots,
but bigger (because the star is younger and generally rotating faster
than the sun) and more stable (no one knows why).
My research in particular
- web page on the larger rotation collaboration
(collaborators, research papers, links to related images)
- sky map with Orion and
Monoceros with NGC 2264 marked. My 45-arcminute fields are about the size
of the white dot marking NGC 2264; we have one field in NGC 2264, and
4 in Orion, surrounding but not including the Trapezium region.
For scale, the whole HST mosaic (multiple pointings) of the Trapezium
region is a little less than a pixel in this graphic.
Astronomy at IR wavelengths and Spitzer
I use near-IR to help determine if a star has a circumstellar disk
Thank you to the Spitzer
Science Center for providing me with
the handouts I distributed at the talk!
Astronomy as a career
I have a separate page for those links.
