Modeling Mass-Loss and Infrared Excess in Large Magellanic Cloud Cepheids
Hilding R. Neilson, Chow-Choong Ngeow, Shashi M. Kanbur +1
The purpose of this preliminary work is to determine if Large Magellanic Cloud (LMC) Cepheids have stellar winds. If a Cepheid undergoes mass loss then at some distance from the st…
The Hydrogen Ionization Front-Stellar Photosphere Interaction and the Period-Color Relations of Variable Stars
S. Kanbur, C. Ngeow, A. Nanthakumar
Recent evidence has emerged that the Cepheid PL relation in the LMC is nonlinear in the sense that the existing data are more consistent with two lines of differing slope with a br…
Reconstructing Cepheid Light Curve with Fourier Techniques II: Catalogue of the Fourier Parameters for OGLE LMC Fundamental Mode Cepheids
C. C. Ngeow, S. Kanbur
In this paper we present a catalogue of the Fourier parameters for the light curves of Large Magellanic Cloud fundamental mode Cepheids in the OGLE database. These Fourier paramete…
Cepheids, supernovae and the value of
M. A. Hendry, S. M. Kanbur
The calibration of the Type Ia supernova distances using HST observations of Cepheid variables is discussed. A new maximum likelihood method of calibration is applied to derive the…
On improved Cepheid distance estimators
Shashi M. Kanbur, Martin A. Hendry
In this paper, we derive a physical argument for the existence of Period-luminosity and period-luminosity-colour relations at maximum light. We examine in detail a sample of Cephei…
