About this problem

The question, scope, and sources behind this Registry record.

Formal question

Track the largest inferred current mass for an individual star under the atmosphere and evolutionary models of the cited study.

Scope & constraints

epoch: 2010 analysis
method: spectroscopy plus evolutionary models
object: R136a1
record: replaceable and model-dependent
quantity: current mass, not initial mass
uncertainty: +80/-35 M_sun
