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…
The Araucaria Project. The Distance to the Sculptor dwarf spheroidal galaxy from infrared photometry of RR Lyrae stars
G. Pietrzynski, W. Gieren, O. Szewczyk +8
We have obtained single-phase near-infrared magnitudes in the J and K bands for a sample of 78 RR Lyrae stars in the Sculptor dSph galaxy. Applying different theoretical and empiri…
The Araucaria Project. The Distance to the Sculptor Group Galaxy NGC 55 from a Newly Discovered Abundant Cepheid Population
G. Pietrzynski, W. Gieren, I. Soszynski +10
We have detected, for the first time, Cepheid variables in the Sculptor Group SB(s)m galaxy NGC 55. From wide-field images obtained in the optical V and I bands during 77 nights in…
The Araucaria Project. An improved distance to the Sculptor spiral galaxy NGC 300 from its Cepheid variables
W. Gieren, G. Pietrzynski, A. Walker +8
In a previous paper, we reported on the discovery of more than a hundred new Cepheid variables in the Sculptor Group spiral NGC 300 from wide-field images taken in the B and V phot…
B,V Photometry of Variable Stars in the Northeast Arm of the Small Magellanic Cloud
Brian Sharpee, Michele Stark, Barton Pritzl +4
B and V photometry has been obtained for variable stars in the northeast arm of the Small Magellanic Cloud (SMC). Periods and lightcurves have been determined for 237 periodic vari…
