Period-Luminosity Relations Derived from the OGLE-III Fundamental Mode Cepheids

C. Ngeow, S. Kanbur, H. Neilson +2

In this Paper, we have derived Cepheid period-luminosity (P-L) relations for the Large Magellanic Cloud (LMC) fundamental mode Cepheids, based on the data released from OGLE-III. W…

Testing Mass Loss in Large Magellanic Cloud Cepheids using Infrared and Optical Observations

Hilding R. Neilson, Chow-Choong Ngeow, Shashi M. Kanbur +1

It has been claimed that Period-Luminosity relations derived from infrared observations of Large Magellanic Cloud (LMC) Cepheids are less dependent on the metallicity of the Cephei…

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…

Non-Linear Cepheid Period-Luminosity Relation and the Interaction of Stellar Photosphere with Hydrogen Ionization Front

C. Ngeow, S. Kanbur

The Cepheid period-luminosity (P-L) relation is regarded as a linear relation (in log[P]) for a wide period range from ~2 to ~100 days. However, several recent controversial works…

The Period-Luminosity Relation for the Large Magellanic Cloud Cepheids Derived from Spitzer Archival Data

C. Ngeow, S. Kanbur

Using Spitzer archival data from the SAGE (Surveying the Agents of a Galaxy's Evolution) program, we derive the Cepheid period-luminosity (P-L) relation at 3.6, 4.5, 5.8 and 8.0 mi…
