Detection of lithium in nearby young late-M dwarfs
N. Phan-Bao, M. S. Bessell, D. Nguyen-Thanh +4
Late M-type dwarfs in the solar neighborhood include a mixture of very low-mass stars and brown dwarfs which is difficult to disentangle due to the lack of constraints on their age…
(sub)Millimeter Emission Lines of Molecules in Born-again Stars
D. Tafoya, J. A. Toalá, W. H. T. Vlemmings +7
The detection and study of molecular gas in born-again stars would be of great importance to understand their composition and chemical evolution. In addition, the molecular emissio…
[WN] central stars of planetary nebulae
H. Todt, B. Miszalski, J. A. Toalá +1

The hot Jupiter of the magnetically-active weak-line T Tauri star V830 Tau
J. -F. Donati, L. Yu, C. Moutou +16
We report results of an extended spectropolarimetric and photometric monitoring of the weak-line T Tauri star V830 Tau and its recently-detected newborn close-in giant planet. Our…
The [Ne III] Jet of DG Tau and its Ionization Scenarios
Chun-Fan Liu, Hsien Shang, Gregory J. Herczeg +1
Forbidden neon emission from jets of low-mass young stars can be used to probe the underlying high-energy processes in these systems. We analyze spectra of the jet of DG Tau obtain…
Discovery of a variable lead-rich hot subdwarf: UVO 0825+15
C. S. Jeffery, A. S. Baran, N. T. Behara +8
UVO0825+15 is a hot bright helium-rich subdwarf which lies in {\it K2} Field 5 and in a sample of intermediate helium-rich subdwarfs observed with {\it Subaru/HDS}. The {\it K2} li…
SCExAO and GPI Band Photometry and Integral Field Spectroscopy of the Young Brown Dwarf Companion to HD 1160
Eugenio V. Garcia, Thayne Currie, Olivier Guyon +51
We present high signal-to-noise ratio, precise photometry and band (\gpiwave~m) spectroscopy of HD 1160 B, a young substellar companion discovered from the Gemini NICI…
Stacking Spectra in Protoplanetary Disks: Detecting Intensity Profiles from Hidden Molecular Lines in HD 163296
Hsi-Wei Yen, Patrick M. Koch, Hauyu Baobab Liu +4
We introduce a new stacking method in Keplerian disks that (1) enhances signal-to-noise ratios (S/N) of detected molecular lines and (2) that makes visible otherwise undetectable w…
Radial decoupling of small and large dust grains in the transitional disk RX J1615.3-3255
Robin Kooistra, Inga Kamp, Misato Fukagawa +56
We present H-band (1.6 μm) scattered light observations of the transitional disk RX J1615.3-3255, located in the ~1 Myr old Lupus association. From a polarized intensity image, tak…
The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
M. A. T. Groenewegen, W. H. T. Vlemmings, P. Marigo +21
Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (…
A correlation between chemistry, polarization and dust properties in the Pipe Nebula starless core FeSt 1-457
Carmen Juárez, Josep M. Girart, Pau Frau +6
Pre-stellar cores within molecular clouds provide the very initial conditions in which stars are formed. We use the IRAM 30m telescope and the PdBI to study the chemical and physic…
RZ Leonis Minoris Bridging between ER Ursae Majoris-Type Dwarf Nova and Novalike System
Taichi Kato, Ryoko Ishioka, Keisuke Isogai +64
We observed RZ LMi, which is renowned for the extremely (~19d) short supercycle and is a member of a small, unusual class of cataclysmic variables called ER UMa-type dwarf novae, i…
Formation and X-ray Emission from Hot Bubbles in Planetary Nebulae. II. Hot bubble X-ray emission
J. A. Toalá, S. J. Arthur
We present a study of the X-ray emission from numerical simulations of hot bubbles in planetary nebulae (PNe). High-resolution, two-dimensional, radiation-hydrodynamical simulation…
