A 3 mm line survey towards the circumstellar envelope of the carbon-rich AGB star IRC+10216 (CW Leo)
Juan Tuo, Xiaohu Li, Jixian Sun +14
We present an unbiased 3 mm spectral line survey (between 84.5 and 115.8 GHz), conducted by the Purple Mountain Observatory 13.7 meter radio telescope, together with updated mo…
Photochemical origin of SiC in the circumstellar envelope of carbon-rich AGB stars revealed by ALMA
Yanan Feng, Xiaohu Li, Tom J. Millar +16
Whether SiC is a parent species, that is formed in the photosphere or as a by-product of high-temperature dust formation, or a daughter species, formed in a chemistry driven by…
Catching a grown-up starfish planetary nebula II. Plasma analysis and central star properties of PC 22
L. Sabin, V. Gómez-Llanos, C. Morisset +4
After performing the morpho-kinematic analysis of the planetary nebula (PN) PC 22, we now present its nebular and stellar analysis. The plasma investigation relies on the novel use…
The born-again planetary nebula A78: an X-ray twin of A30
J. A. Toalá, M. A. Guerrero, H. Todt +8
We present the XMM-Newton discovery of X-ray emission from the planetary nebula (PN) A78, the second born-again PN detected in X-rays apart from A30. These two PNe share similar sp…
Expansion of hydrogen-poor knots in the born-again planetary nebulae A30 and A78
Xuan Fang, Martin A. Guerrero, Ramon A. Marquez-Lugo +8
We analyze the expansion of hydrogen-poor knots and filaments in the born-again planetary nebulae A30 and A78 based on Hubble Space Telescope (HST) images obtained almost 20 yr apa…
