Photographic photometry of Magellanic Cloud cepheids
… (B,V) light curves of 213 LMC and 180 SMC cepheids (and W Virginis stars) have been obtained and the relevant light-curve parameters derived. Comparison of this work with stars in common with photoelectric data indicate that the <V> and (<B> - <V>) magnitudes differ from their photoelectric …

Improving the extragalactic distance scale using Cepheids in M33
Cepheids have been used as distance indicators for almost a century. Through their well defined period-luminosity relation, their distance can be found from their period of pulsation alone. However, in recent years, an important uncertainty has arisen in its calibration, namely the effect of …

THE CEPHEIDS OF M33: DISTANCE AND METALLICITY EFFECTS THROUGH SLOAN FILTERS
Cepheids are a class of variable stars that undergo regular pulsations in size and brightness. There exists a strong correlation between the period of pulsation and the average intrinsic brightness of a Cepheid; this correlation is known as the period-luminosity relation, or Leavitt Law. It is this …
