POLARIS, SMALL-AMPLITUDE CEPHEID WITH UNIQUE PHYSICAL PECULIARITIES

POLARIS, SMALL-AMPLITUDE CEPHEID WITH UNIQUE PHYSICAL PECULIARITIES

We present the results of our analysis of spectroscopic observations of α UMi (Polaris) obtained in 1994 (5 spectra) and 2001-2004 (30 spectra) and frequency analysis of all Polaris RV data collected during last 120 years. This analysis has confirmed the proposition about its overtone pulsations i...
