A Natural Laboratory for Astrochemistry, a Variable Protostar B335

Autor: Lee, Jeong-Eun, Evans II, Neal J., Baek, Giseon, Kim, Chul-Hwan, Noh, Jinyoung, Yang, Yao-Lun

Emission lines from complex organic molecules in B335 were observed in four epochs, spanning a luminosity burst of about 10 years duration. The emission lines increased dramatically in intensity as the luminosity increased, but they have decreased on
