Radio Frequency Models of Novae in eruption. I. The Free-Free Process in Bipolar Morphologies

V. A. R. M. Ribeiro, L. Chomiuk, U. Munari +6

Observations of novae at radio frequencies provide us with a measure of the total ejected mass, density profile and kinetic energy of a nova eruption. The radio emission is typical…

Near Infrared Spectroscopic Study of V1647 Ori

S. D. Brittain, T. W. Rettig, T. Simon +2

We present new high-resolution infrared echelle spectra of V1647 Ori, the young star that illuminates McNeil's nebula. From the start, V1647 Ori has been an enigmatic source that h…

O VI Observations of the Onset of Convection Zones in Main-Sequence A Stars

J. E. Neff, T. Simon

If magnetic activity in outer stellar atmospheres is due to an interplay between rotation and subsurface convection, as is generally presumed, then one would not expect to observe…

Post-Outburst Observations of V1647 Ori: Detection of a Brief Warm, Molecular Outflow

Sean Brittain, Terrence Rettig, Theodore Simon +4

We present new observations of the fundamental ro-vibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil's Nebula. Previous spectra, acquired…

Warm Gas in the Inner Disks around Young Intermediate Mass Stars

Sean Brittain, Theodore Simon, Joan Najita +1

The characterization of gas in the inner disks around young stars is of particular interest because of its connection to planet formation. In order to study the gas in inner disks,…

Dust Stratification in Young Circumstellar Disks

T. Rettig, S. Brittain, Theodore Simon +4

We present high-resolution infrared spectra of four YSOs (T Tau N, T Tau S, RNO 91, and HL Tau). The spectra exhibit narrow absorption lines of 12CO, 13CO, and C18O as well as broa…
