Period-Luminosity Relation for Type II Cepheids (2009)
Matsunaga, Noriyuki, Feast, Michael W., Menzies, John W.
We have estimated JHKs magnitudes corrected to mean intensity for LMC type II Cepheids found in the OGLE-III survey. Period-luminosity relations (PLRs) are derived in JHKs as well as in a...
Period-Luminosity Relations for Type II Cepheids and their Application (2009)
Matsunaga, Noriyuki, Feast, Michael W., Menzies, John W.
JHKs magnitudes corrected to mean intensity are estimated for LMC type II Cepheids in the OGLE-III survey. Period-luminosity (PL) relations are derived in JHKs as well as in a reddening-free VI...
AGB Stars in the Fornax Dwarf Spheroidal Galaxy (2008)
Whitelock, Patricia A., Menzies, John W., Feast, Michael W., Matsunaga, Noriyuki, Tanabe, Toshihiko, Ita, Yoshifusa
We report on a multi-epoch study of the Fornax dwarf spheroidal galaxy, made with the Infrared Survey Facility, over an area of about 42'x42'. The colour-magnitude diagram shows a broad...
Benedict, G. Fritz, McArthur, Barbara E., Feast, Michael W., Barnes, Thomas G., Harrison, Thomas E., Patterson, Richard J., ...
(abridged) We present new absolute trigonometric parallaxes and relative proper motions for nine Galactic Cepheid variable stars: l Car, zeta Gem, beta Dor, W Sgr, X Sgr, Y Sgr, FF Aql, T Vul, and RT...
The period-luminosity relation for type II Cepheids in globular clusters (2006)
Matsunaga, Noriyuki, Fukushi, Hinako, Nakada, Yoshikazu, Tanabe, Toshihiko, Feast, Michael W., Menzies, John W., ...
We report the result of our near-infrared observations (JHKs) for type II Cepheids (including possible RV Tau stars) in galactic globular clusters. We detected variations of 46 variables in 26...
Carbon-Rich Mira Variables: Radial Velocities and Distances (2006)
Menzies, John W., Feast, Michael W., Whitelock, Patricia A.
Optical radial velocities have been measured for 38 C-type Mira variables. These data together with others in the literature are used to study the differences between optical and CO mm observations...
Carbon-Rich Mira Variables: Kinematics and Absolute Magnitudes (2006)
Feast, Michael W., Whitelock, Patricia A., Menzies, John W.
The kinematics of galactic C-Miras are discussed on the basis of the bolometric magnitudes and radial velocities of Papers I and II of this series. Differential galactic rotation is used to derive a...
V838 Mon: light echo evolution and distance estimate (2005)
Crause, Lisa A., Lawson, Warrick A., Menzies, John W., Marang, Fred
Following its 2002 February eruption, V838 Mon developed a light echo that continues to expand and evolve as light from the outburst scatters off progressively more distant circumstellar and/or...
Discovery of the optical counterpart and early optical observations of GRB 990712 (2000)
Sahu, Kailash C., Vreeswijk, P. M., Bakos, Gaspar A., Menzies, John W., Bragaglia, Angela, Frontera, Filippo, ...
We present the discovery observations of the optical counterpart of the gamma-ray burst GRB 990712 taken 4.16 hr after the outburst and discuss its light curve observed in the V, R, and I bands...
