Centimeter-wave continuum radiation from the rho Ophiuchi molecular cloud
Simon Casassus, Clive Dickinson, Kieran Cleary +8
The rho Oph molecular cloud is undergoing intermediate-mass star formation. UV radiation from its hottest young stars heats and dissociates exposed layers, but does not ionize hydr…
A Three-Decade Outburst of the LMC Luminous Blue Variable R127 Draws to a Close
Nolan R. Walborn, Otmar Stahl, Roberto C. Gamen +7
The paradigmatic Luminous Blue Variable R127 in the Large Magellanic Cloud has been found in the intermediate, peculiar early-B state, and substantially fainter in visual light, si…
Interstellar 12C/13C from CH+ absorption lines: Results from an extended survey
O. Stahl, S. Casassus, T. L. Wilson
The 12C/13C isotope ratio in the interstellar medium (ISM), and its evolution with time, is an important tracer of stellar yields. Spatial variations of this ratio can be used to s…
A multispectral view of the periodic events in eta Carinae
A. Damineli, D. J. Hillier, M. F. Corcoran +13
A full description of the 5.5-yr low excitation events in Eta Carinae is presented. We show that they are not as simple and brief as previously thought, but a combination of two co…
Variable Unidentified Emission Near 6307 AA in Eta Carinae
J. C. Martin, K. Davidson, F. Hamann +2
We have discovered a conspicuous unidentified variable feature near 6307 AA in the spectrum of Eta Carinae which is spatially unresolved from the central star and its wind (r < 200…
Interstellar 12C/13C ratios through CH+ ll 3957,4232 absorption in local clouds: incomplete mixing in the ISM
S. Casassus, O. Stahl, T. L. Wilson
The 12C/13C isotope ratio is a tracer of stellar yields and the efficiency of mixing in the ISM. 12CH+/13CH+ is not affected by interstellar chemistry, and is the most secure way o…
