Correlation between Interstellar Polarization and Dust Temperature: Alignment of Grains by Radiative Torques is Ubiquitous?

Masafumi Matsumura, Youko Kameura, Koji S. Kawabata +3

We investigate the efficiency of interstellar polarization $p_{\lambda }/A_{\lambda }$ where $p_{\lambda }$ is the fractional linear polarization and $A_{\lambda }$ is extinction, in 16 lines of sight as a function o…
