When Cold Radial Migration is Hot: Constraints from Resonant Overlap
Kathryne J. Daniel, David A. Schaffner, Fiona McCluskey +2
It is widely accepted that stars in a spiral disk, like the Milky Way's, can radially migrate on order a scale length over the disk's lifetime. With the exception of cold torquing,…
Constraints on Radial Migration in Spiral Galaxies - II. Angular momentum distribution and preferential migration
Kathryne J. Daniel, Rosemary F. G. Wyse
The orbital angular momentum of individual stars in galactic discs can be permanently changed through torques from transient spiral patterns. Interactions at the corotation resonan…
An Approximate Analytic Model of a Star Cluster with Potential Escapers
Kathryne J. Daniel, Douglas C. Heggie, Anna Lisa Varri
In the context of a star cluster moving on a circular galactic orbit, a "potential escaper" is a cluster star that has orbital energy greater than the escape energy, and yet is con…
Gemini Deep Deep Survey VI: Massive Hdelta-strong galaxies at z=1
Damien Le Borgne, Roberto Abraham, Kathryne Daniel +11
We show that there has been a dramatic decline in the abundance of massive galaxies with strong Hdelta stellar absorption lines from z=1.2 to the present. These ``Hdelta-strong'',…
Simultaneous Chandra and VLA Observations of Young Stars and Protostars in rho Ophiuchus Cloud Core A
Marc Gagne, Stephen L. Skinner, Kathryne J. Daniel
A 96-ks Chandra X-ray observation of rho Ophiuchus cloud core A detected 87 sources, of which 60 were identified with counterparts at other wavelengths. The X-ray detections includ…
