Kinematical Investigation of Possible Fast Collimated Outflows in Twelve Planetary Nebulae
J. S. Rechy-García, M. A. Guerrero, S. Duarte Puertas +3
A significant fraction of planetary nebulae (PNe) exhibit collimated outflows, distinct narrow kinematical components with notable velocity shifts with respect to the main nebular…
ALMA Observations of the Extraordinary Carina Pillars: HH 901/902
Geovanni Cortes-Rangel, Luis A. Zapata, Jesus A. Toala +4
We present Atacama Large Millimeter/Submillimeter Array (ALMA) 1.3 mm continuum and CO(21), ND(32), CS(54), and CO(21) line sensitive and…
Dissecting the hot bubbles in LMC-N57 with XMM-Newton
I. Ramírez-Ballinas, J. Reyes-Iturbide, J. A. Toalá +1
We present a study of the diffuse X-ray emission from the star forming region LMC-N 57 in the Large Magellanic Cloud (LMC). We use archival XMM-Newton observations to unveil in det…
Variable Hard X-ray Emission From the Central Star of the Eskimo Nebula
Martin A Guerrero, Jesus A Toala, You-Hua Chu
The central star of NGC 2392 shows the hardest X-ray emission among central stars of planetary nebulae (CSPNe). The recent discovery of a spectroscopic companion with an orbital pe…
The Nearby Evolved Stars Survey: I. JCMT/SCUBA-2 Sub-millimetre detection of the detached shell of U Antliae
Thavisha E. Dharmawardena, Francisca Kemper, Sundar Srinivasan +24
We present the highest resolution single-dish submillimetre observations of the detached shell source U Antliae to date. The observations were obtained at $450~\micron$ and $850~\m…
Hidden IR structures in NGC 40: signpost of an ancient born-again event
J. A. Toalá, G. Ramos-Larios, M. A. Guerrero +1
We present the analysis of infrared (IR) observations of the planetary nebula NGC 40 together with spectral analysis of its [WC]-type central star HD 826. Spitzer IRS observations…
