ALMA 2D super-resolution imaging survey of Ophiuchus Class I/flat spectrum/II disks. II. Statistical analysis of stellar and disk properties

Ayumu Shoshi, Masayuki Yamaguchi, Takayuki Muto +5

We present a statistical study of stellar and dust disk properties for young stellar objects in the Ophiuchus star-forming region. Building on our previous paper (Shoshi et al. 202…

HOPS-288: A Laboratory for Complex Organics in Proto-multiple Systems

Shih-Ying Hsu, Nadia M. Murillo, Chin-Fei Lee +21

Complex organic molecules (COMs) in young stellar objects (YSOs) have attracted significant attention in recent years due to their potential connection to pre-biotic chemistry and…

Probing the Physical and Chemical Characteristics of an Extremely Early Class 0 Protostar in G204.4-11.3A2-NE

Hsuan-I, Chou, Naomi Hirano +1

We have observed the low-mass molecular cloud core G204.4-11.3A2-NE (G204NE) in the direction of Orion B giant molecular cloud with the Atacama Large Millimeter/submillimeter Array…

Detection of CH3+ in the O-rich planetary nebula NGC 6302

Charmi Bhatt, Jan Cami, Els Peeters +33

Planetary nebulae are sites where ejected stellar material evolves into complex molecules, but the precise physical conditions and chemical routes that govern these processes are u…

Unveiling Stellar Feedback and Cloud Structure in the Ophiuchi A Region with ALMA and JWST: Discovery of Substellar Cores, CO Striations, and Protostellar Outflows

Fumitaka Nakamura, Ryohei Kawabe, Shuo Huang +9

In clustered star-forming regions, stellar feedback-such as HII regions/photon-dominated regions (PDRs), and protostellar jets/outflows-shapes cloud structures and influences star…

The JWST/MIRI view of the planetary nebula NGC 6302 I.: a UV irradiated torus and a hot bubble triggering PAH formation

Mikako Matsuura, Kevin Volk, Patrick Kavanagh +34

NGC 6302 is a spectacular bipolar planetary nebula (PN) whose spectrum exhibits fast outflows and highly ionized emission lines, indicating the presence of a very hot central star…
