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…

Cepheid Period-Luminosity Relations: Galactic vs. LMC and the Results from t-Test
C. Ngeow, S. Kanbur
The period-luminosity (PL) relation for Galactic Cepheids is derived with recent independent distance measurements taken from literature. Our PL relation confirms the work of Tamma…
