New Evidence Supporting Membership for TW Nor in Lynga 6 and the Centaurus Spiral Arm
Daniel J. Majaess, David G. Turner, Christian Moni Bidin +10
The putative association between the 10.8 d classical Cepheid TW Nor and the open cluster Lynga 6 has generated considerable debate in the literature. New JHKs photometry in tandem…
A New Collisional Ring Galaxy at z = 0.111: Auriga's Wheel
Blair C. Conn, Anna Pasquali, Emanuela Pompei +4
We report the serendipitous discovery of a collision ring galaxy, identified as 2MASX J06470249+4554022, which we have dubbed 'Auriga's Wheel', found in a SUPRIME-CAM frame as part…
WR 110: A Single Wolf-Rayet Star With Corotating Interaction Regions In Its Wind?
A. -N. Chené, A. F. J. Moffat, C. Cameron +13
A 30-day contiguous photometric run with the MOST satellite on the WN5-6b star WR 110 (HD 165688) reveals a fundamental periodicity of P = 4.08 +/- 0.55 days along with a number of…
A 10-hour period revealed in optical spectra of the highly variable WN8 Wolf-Rayet star WR 123
A. -N. Chené, C. Foellmi, S. V. Marchenko +6
Aims. What is the origin of the large-amplitude variability in Wolf-Rayet WN8 stars in general and WR123 in particular? A dedicated spectroscopic campaign targets the ten-hour peri…
The WR 140 periastron passage 2009: first results from MONS and other optical sources
R. Fahed, A. F. J. Moffat, J. Zorec +29
We present the results from the spectroscopic follow-up of WR140 (WC7 + O4-5) during its last periastron passage in January 2009. This object is known as the archetype of colliding…
