Supernovae 2011bs-2011by.

PRIETO J.L.

Abstract (from CDS):

J. L. Prieto, Carnegie Observatories, reports that optical spectra (range 380-920 nm; resolution 0.7 nm) were obtained of the above variables with the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory on Apr. 9 and 11 UT, showing that all are indeed supernovae. After cross-correlation with a library of supernova spectra using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), the following spectral classes, redshifts, and approximate phases (in days after maximum light) were obtained:

---------------------------------------------------------------------------— SN Type Redshift phase 2011bs II 0.036 +16 2011bt Ia 0.114 +15 2011bu Ia 0.149 +10 2011bv IIb 0.077 + 1 2011bw Ia 0.089 +36 2011bx Ia 0.058 + 1 2011by II 0.03 \rule
