Summary
HOPS 198 opens about 80 degrees eastward but only 30 degrees westward.
Modeling of the protostellar outflow HOPS 198 attributes its asymmetric cavity chiefly to ambient density: the western core is estimated at 1.5 to 2.8 times the eastern density. The work, accepted by Astronomy & Astrophysics, supports a density-driven opening rather than documenting a transient event.
Why it matters
HOPS 198 opens about 80 degrees eastward but only 30 degrees westward.
Limits and context
No additional limitation was separately recorded.
Key claims
HOPS 198 opens about 80 degrees eastward but only 30 degrees westward.
