The spectroscopic evolution of the recurrent nova T Pyxidis during its 2011 outburst. II.The optically thin phase and the structure of the ejecta in recurrent novae
S. N. Shore, G. J. Schwarz, I. De Gennaro Aquino +4
We continue our study of the physical properties of the recurrent nova T Pyx, focussing on the structure of the ejecta in the nebular stage of expansion during the 2011 outburst. T…
The Stony Brook / SMARTS Atlas of mostly Southern Novae
Frederick M. Walter, Andrew Battisti, Sarah E. Towers +2
We introduce the Stony Brook / SMARTS Atlas of (mostly) Southern Novae. This atlas contains both spectra and photometry obtained since 2003. The data archived in this atlas will fa…
Accretion dynamics in the classical T Tauri star V2129 Oph
S. H. P. Alencar, J. Bouvier, F. M. Walter +9
We analyze the photometric and spectroscopic variability of the classical T Tauri star V2129 Oph over several rotational cycles to test the dynamical predictions of magnetospheric…
The Brown Dwarf Kinematics Project (BDKP). III. Parallaxes for 70 Ultracool Dwarfs
Jacqueline K. Faherty, Adam J. Burgasser, Frederick M. Walter +6
We report parallax measurements for 70 ultracool dwarfs (UCDs). Using both literature values and our sample, we report new polynomial relations between spectral type and M.…
Is FS Tau B Driving an Asymmetric Jet?
Chun-Fan Liu, Hsien Shang, Tae-Soo Pyo +6
FS Tau B is one of the few T Tauri stars that possess a jet and a counterjet as well as an optically-visible cavity wall. We obtained images and spectra of its jet-cavity system in…
