Webvery small angles, the radius of Cas A is approximately equal to the arc length transcribed by these lines of sight. Therefore, the small angle formula is as follows, where is in radians: = (radius of Cas A) / (distance to Cas A) Using the small angle formula and a distance to Cas A of ~11,100 light years, find the radius of Cas A in meters.

The majority of massive stars are likely members of binary star systems (e.g., Abt and Levy, 1978 ). Furthermore, close binary systems are likely the progenitors of many core-collapse SNe. jira プロジェクト 移行Webthe expansion index, m (where the supernova radius is R ∝ tm and t is the age after explosion, see Chevalier 1982a), corre-sponding to four different expansion periods.
