Protosolar D-to-H abundance and one part-per-billion PH in the coldest brown dwarf
Melanie J. Rowland, Caroline V. Morley, Brittany E. Miles +24
The coldest Y spectral type brown dwarfs are similar in mass and temperature to cool and warm (200 -- 400 K) giant exoplanets. We can therefore use their atmospheres as proxi…
Analysis of the 3.2-3.3 m Interstellar Absorption Feature on Three Milky Way Sightlines
L. S. Bernstein, T. R. Geballe
We report new analyses of spectra of the m absorption feature observed in the diffuse interstellar medium toward three Milky Way sources: 2MASS (2M17…
Analysis of the first infrared spectrum of quasi-bound H2 line emission in Herbig-Haro 7
Evelyne Roueff, Michael G. Burton, Thomas R. Geballe +1
Context. Highly excited molecular hydrogen H2 has been observed in many regions of shocked molecular gas. A recently published -band spectrum of Herbig-Haro 7 (HH7) contains sev…
Neutron-Capture Element Abundances in Magellanic Cloud Planetary Nebulae
A. L. Mashburn, N. C. Sterling, S. Madonna +3
We present near-infrared spectra of ten planetary nebulae (PNe) in the Large and Small Magellanic Clouds (LMC and SMC), acquired with the FIRE and GNIRS spectrometers on the 6.5-m…
Herschel/HIFI observations of interstellar OH+ and H2O+ towards W49N: a probe of diffuse clouds with a small molecular fraction
D. A. Neufeld, J. R. Goicoechea, P. Sonnentrucker +50
We report the detection of absorption by interstellar hydroxyl cations and water cations, along the sight-line to the bright continuum source W49N. We have used Herschel's HIFI ins…
Do Hydrogen-deficient Carbon Stars have Winds?
T. R. Geballe, N. Kameswara Rao, Geoffrey C. Clayton
We present high resolution spectra of the five known hydrogen-deficient carbon (HdC) stars in the vicinity of the 10830 Angstrom line of neutral helium. In R Coronae Borealis (RCB)…
