OGLE-IV Period-Luminosity relation of the LMC: an analysis using mean and median magnitudes
Jaime Muñoz, Alejandro García-Varela, Santiago Henao-Castellanos +2
TThe Period-Luminosity (PL) relation for Cepheid variable stars in the Large Magellanic Cloud (LMC) is crucial for distance measurements in astronomy. This study analyzes the impac…
The influential effect of blending, bump, changing period and eclipsing Cepheids on the Leavitt law
A. García-Varela, J. R. Muñoz, B. E. Sabogal +2
The investigation of the non-linearity of the Leavitt law is a topic that began more than seven decades ago, when some of the studies in this field found that the Leavitt law has a…
The Variable Stars from the OGLE-III Shallow Survey in the Large Magellanic Cloud
K. Ulaczyk, M. K. Szymański, A. Udalski +8
We describe variable stars found in the data collected during the OGLE-III Shallow Survey covering the I-band magnitude range from 9.7 mag to 14.5 mag. The main result is the exten…
Photometric Maps Based on the OGLE-III Shallow Survey in the Large Magellanic Cloud
K. Ulaczyk, M. K. Szymanski, A. Udalski +8
We present photometric maps based on data from the shallow survey in the Large Magellanic Cloud performed as the supplementary project during the third phase of the Optical Gravita…
The Araucaria Project. First Cepheid Distance to the Sculptor Group Galaxy NGC 7793 from Variables discovered in a Wide-Field Imaging Survey
G. Pietrzynski, W. Gieren, M. Hamuy +12
We have detected, for the first time, Cepheid variables in the Sculptor Group spiral galaxy NGC 7793. From wide-field images obtained in the optical V and I bands on 56 nights in 2…
The Araucaria Project. The Distance to the Sculptor Galaxy NGC 247 from Near-Infrared Photometry of Cepheid Variables
W. Gieren, G. Pietrzynski, I. Soszynski +7
We have obtained deep near-infrared images in J and K filters of four fields in the Sculptor Group spiral galaxy NGC 247 with the ESO VLT and ISAAC camera. For a sample of ten Ceph…
The Araucaria Project: The Distance to the Sculptor Group Galaxy NGC 247 from Cepheid Variables Discovered in a Wide-Field
A. Garcia-Varela, G. Pietrzynski, W. Gieren +9
We report on the discovery of a Cepheid population in the Sculptor Group spiral galaxy NGC 247 for the first time. On the basis of wide-field images collected in photometric survey…
