TL;DR: In this article, the authors performed a deep search for molecular oxygen, through the 2₁−0.5 GHz rotational transition at 234 GHz, towards the warm compact gas surrounding the nearby Class 0 protostar IRAS 16293-2422 B with the ALMA interferometer, and obtained a [O₂]/[CH₃OH] abundance ratio lower than 2−5, depending on the assumed Tex, a three to four times lower abundance than the [O¹OH]- ratio of 5−15 found
