A One-Sided Sulfur Arc Marked a Possible New Giant Planet
ALMA mapped localized heating in the edge-on Gomez’s Hamburger disk alongside asymmetry, a disk wind and a gas overdensity.
Summary
ALMA mapped localized heating in the edge-on Gomez’s Hamburger disk alongside asymmetry, a disk wind and a gas overdensity.
High-resolution ALMA maps of the edge-on Gomez’s Hamburger disk found a narrow one-sided arc of sulfur monoxide near a previously identified gas overdensity. The authors say the localized heating could surround an early giant protoplanet or a disk fragment. Carbon-monoxide observations also show non-Keplerian emission consistent with a disk wind, while the continuum is asymmetric north to south. A revised distance of 139 plus or minus 24 parsecs places the system near Scorpius–Centaurus. The sulfur chemistry is a candidate tracer, not a direct detection of a planet.
