Given their strong stellar winds, Wolf-Rayet (WR) stars exhibit emission line spectra that are predominantly formed in expanding atmospheric layers. The description of the wind vel…
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…
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…
