Abstract We present the Atacama Large Millimeter/submillimeter Array observations of linearly polarized 1.1 mm continuum emission at ∼0.″14 (55 au) resolution and CO ( J = 2−1) ∼1.″5 (590 toward one prestellar (MMS 4), four Class 0 1, MMS 3, 5, 6), I 7), flat-spectrum 2) sources in Orion Molecular Cloud 3 region. The dust disk-like structures clear outflows are detected all except for 4. diameters these structures, ranging from 16 to 97 au, estimated based on deconvolved full width half...
The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability high-quality data, leaving size estimates reliant on spherical shape assumptions. Such approximations introduce significant uncertainties propagating, for example, into density determinations or thermophysical and compositional studies, affecting our understanding asteroid properties. This work targets studied main-belt most...
Abstract We present ∼0.″2 (∼80 au) resolution observations of the CO(2–1) and SiO(5–4) lines made with Atacama large millimeter/submillimeter array toward an extremely young intermediate-mass protostellar source ( t dyn < 1000 yr), MMS 1 located in Orion Molecular Cloud-3 region. have successfully imaged a very compact CO molecular outflow associated 1, having deprojected lobe sizes ∼1800 au (redshifted lobe) ∼2800 (blueshifted lobe). also detected (≲1000 collimated SiO jet within...
