Abstract (from CDS):

N. Morrell, M. Hamuy, and G. Folatelli, Carnegie Supernova Project; and F. Olivares, University of Chile, report that spectra (range 380-930 nm) were obtained on Feb. 4 and 8 UT with the Las Campanas 2.5-m du Pont Telescope (+ WFCCD spectrograph), showing that SNe 2005Q, 2005Y, 2005Z, and 2005ad (cf. IAUC 8473, 8476, 8479) are all of type II. SNe 2005ad, 2005Z, and 2005Q display blue continua with strong P-Cyg profiles in the Balmer lines and He I 587.6-nm, indicative of young events. SN 2005ad seems to be very young, based on the very blue continuum. SN 2005Y shows the Balmer lines and the Fe II 516.9-nm absorption, implying a more evolved event. The expansion velocities, derived from the minimum of the H_beta absorption (assuming for the parent galaxies the recession velocities listed in the NED database) are: 2005Q, 11500 km/s; 2005Y, 6800; 2005Z, 11600; 2005ad, 7400. A spectrum of SN 2005S reveals it to be a type-Ia supernova, 2-3 weeks after maximum light.
