M1-92: AGB interruption and isotopic ratio paradox. Chemistry and morpho-kinematics from improved shapemol modelling

E. Masa, J. Alcolea, M. Santander-García +5

The shaping of planetary nebulae on their evolution from asymptotic giant branch circumstellar envelopes to their final, most often axisymmetrical, form is still a process with man…

CH3CCH as a thermometer in warm molecular gas

Yuqiang Li, Junzhi Wang, Juan Li +9

Kinetic temperature is a fundamental parameter in molecular clouds. Symmetric top molecules, such as NH and CHCCH, are often used as thermometers. However, at high temperat…

Probing the Molecular Hearts of Extreme Bipolar Planetary Nebulae with ALMA

Paula Moraga Baez, Joel H. Kastner, Jesse Bublitz +6

We present results from a program of Atacama Large Millimeter Array (ALMA) 1.3 mm (Band 6) molecular line mapping of a sample of nearby, bipolar/pinched-waist, molecule-rich PNe (N…

JWST/NIRCam imaging of the Bipolar Planetary Nebula NGC 6537: the (Infra)red Spider, Revealed

Joel Kastner, Paula Moraga Baez, Bruce Balick +5

We present James Webb Space Telescope (JWST) near-infrared (NIRCam) Br, H, [Fe II], and PAH imaging of the molecule-rich, high-excitation bipolar planetary nebula (PN) NGC…

High-Speed Outflows and Dusty Disks during the AGB to PN Transition: The PANORAMA survey

Raghvendra Sahai, Javier Alcolea, Bruce Balick +15

As mass-losing asymptotic giant branch (AGB) stars evolve to planetary nebulae (PNe), the mass outflow geometries transform from nearly spherical to extreme aspherical. The physica…

A Yebes W band Line Survey towards an Unshocked Molecular Cloud of Supernova Remnant 3C391: Evidence of Cosmic-Ray-Induced Chemistry

Tian-Yu Tu, Prathap Rayalacheruvu, Liton Majumdar +3

Cosmic rays (CRs) have strong influences on the chemistry of dense molecular clouds (MCs). To study the detailed chemistry induced by CRs, we conducted a Yebes W band line survey t…
