NED Abstract

Copyright by Royal Astronomical Society. 2010MNRAS.403L..11M Type II-P supernovae as standardized candles: improvements using near-infrared data Maguire, K.; Kotak, R.; Smartt, S. J.; Pastorello, A.; Hamuy, M.; Bufano, F. Abstract. ABSTRACT We present the first near-infrared Hubble diagram for Type II-P supernovae (SNe), to further explore their value as distance indicators. We use a modified version of the standardized candle method, which relies on the tight correlation between the absolute magnitudes of Type II-P SNe and their expansion velocities during the plateau phase. Although our sample contains only 12 II-P SNe and they are necessarily local (z < 0.02), we demonstrate using near-infrared JHK photometry that it may be possible to reduce the scatter in the Hubble diagram to 0.1-0.15 mag. While this is potentially similar to the dispersion seen for Type Ia SNe, we caution that this needs to be confirmed with a larger sample of II-P SNe in the Hubble flow. Key words: supernovae: general, galaxies: general, distance scale
