Constraining properties of dust formed in Wolf-Rayet binary WR 112 using mid-infrared and millimeter observations

Donglin Wu, Yinuo Han, Peredur M. Williams +9

Binaries that host a carbon-rich Wolf-Rayet (WC) star and an OB-type companion can be copious dust producers. Yet the properties of dust, particularly the grain size distribution,…

A Critical Examination of the PAH Hypothesis

Alan T. Tokunaga, Lawrence S. Bernstein, Takashi Onaka

The polycyclic aromatic hydrocarbon (PAH) hypothesis proposes that the aromatic infrared bands (AIBs) observed at 3.3, 6.2, 7.7, 8.6, 11.3, and 12.7 mic originate from gas-phase PA…

The Aromatic Infrared Bands around the Wolf-Rayet Binary WR140 Revealed by JWST

Kotomi Taniguchi, Ryan M. Lau, Takashi Onaka +12

We have analyzed the aromatic infrared bands (AIBs) in the 6-11.2 m range around the Wolf-Rayet binary WR140 (d=1.64 kpc) obtained with the James Webb Space Telescope (JWST) Mi…

The JCMT BISTRO-3 Survey: Variation of magnetic field orientations on parsec and sub-parsec scales in the massive star-forming region G28.34+0.06

Jihye Hwang, Kate Pattle, Chang Won Lee +35

Magnetic fields play a significant role in star-forming processes on core to clump scales. We investigate magnetic field orientations and strengths in the massive star-forming clum…

The JCMT BISTRO Survey: Unveiling the Magnetic Fields around Galactic Center

Meng-Zhe Yang, Shih-Ping Lai, Janik Karoly +40

We acquired 450 μm and 850 μm dust continuum polarization observations toward the inner region of the Central Molecular Zone (CMZ) as part of the B-Fields In Star-Forming Region…

The JCMT BISTRO Survey: Magnetic Fields Align with Orbital Structure in the Galactic Center

Janik Karoly, Derek Ward-Thompson, Kate Pattle +29

We present the magnetic field in the dense material of the Central Molecular Zone (CMZ) of the Milky Way, traced in 850 m polarized dust emission as part of the James Clerk Max…
