An article published in the journal “Nature Astronomy” reports the observation of natural masers that revealed a heat wave in the protostar G358.93-0.03-MM1, or simply G358-MM1. A team of researchers led by Ross Burns of NAOJ (National Astronomical Observatory of Japan) carried out the detections as part of the M2O (Maser Monitoring Organization) network of astronomers, specialized in the study of astrophysical masers to understand their nature. In the specific case, it’s a massive protostar and the heat wave coming from it confirms that this type of star passes through a non-linear formation process.
