Abstract (from CDS):

We report on the discovery of Cepheids in the spiral galaxy NGC 2841, based on observations made with the Wide Field Planetary Camera 2 on board the Hubble Space Telescope. NGC 2841 was observed over 12 epochs using the F555W filter and over five epochs using the F814W filter. Photometry was performed using the DAOPHOT/ALLFRAME package. We discovered a total of 29 variables, including 18 high-quality Cepheids with periods ranging from 15 to 40 days. Period-luminosity relations in the V and I bands, based on the high-quality Cepheids, yield a reddening-corrected distance modulus of 30.74±0.23 mag, which corresponds to a distance of 14.1±1.5 Mpc. Our distance is based on an assumed LMC distance modulus of µ0=18.50±0.10 mag (D=50±2.5 kpc) and a metallicity dependence of the Cepheid P-L relation of γVI=-0.2±0.2 mag dex–1.
