Massive gas reservoirs surround three stellar cores revealed by observations, with the brightest core, MM1, holding an estimated 24.6 solar masses of gas, according to Scinexx.
Scinexx reported that MM2 contains about 8.4 solar masses, while MM3 holds only roughly 5.2 solar masses. These figures measure the core masses derived from dust radiation rather than the mass of stars that have already formed.
MM2 Produces a Collimated Bipolar Gas Jet
The strongest matter outflow originates from MM2 despite its smaller mass compared to MM1.
Scinexx said that a collimated, bipolar gas jet emerges from MM2, showing silicon monoxide signal velocity differences of up to about 25 kilometers per second compared to the surrounding gas.
Sulfur monoxide, formaldehyde, and methanol trace a broader region of stirred and heated gas around this jet. A previously observed hydrogen knot named MHO 2463 lies along the approximate extension of the outflow axis, which could point to an older ejection of matter.
MM3 Displays the Most Diverse Molecular Spectrum
The chemically richest core is MM3, which displays the most diverse spectrum of molecular signals among the three objects.
Scinexx reported that signals from methanol and methyl cyanide indicate warm and dense gas within MM3, alongside a group of methanol masers operating at 6.7 gigahertz.
Spectral lines from methyl cyanide yielded derived temperatures of approximately 273 Kelvin for MM3, about 257 Kelvin for MM2, and roughly 165 Kelvin for MM1. These molecular complexities and maser signatures provide additional clues regarding the evolutionary state of MM3.
Evolutionary Sequences
These findings fit a potential evolutionary sequence running from a chemically less developed MM1 through the actively outflowing MM2 to the molecule-rich hot core MM3.
This suggests multiple developmental stages of massive stellar germs could coexist within a single fragmenting gas cloud.
Direct age measurements remain unconfirmed because estimated core masses depend entirely on assumptions regarding dust temperatures and properties. Total radiation output and ionized gas quantities were not resolved individually for the three cores, leaving their exact developmental timelines open to interpretation.
