Abstract ▼ AI-Helper

Using the spectroscopic data secured with the Hamilton Echelle Spectrograph at Lick Observatory, we found the physical condition of the planetary Nebula NGC 6210. The spectral line profiles of the permitted and forbidden lines have been analyzed using IRAF and StarLink/Dipso. The hydrogen number densities ($N_H$) are 2,000-20,000 $cm^{-3}$, and the electron temperatures are 8,100-10,300 K based on the forbidden lines. The expansion velocities, derived from the Full Width at Half Maximum (FWHM) and the double peak of the line profiles, are in the range of 10 to $45\;kms^{-1}$. The expansion velocities imply a shell structure with an accelerated nebular gas. We also derived abundances from the permitted lines of CII, CIII, NII, NIII, OII, and OIII, which may have been formed through the fluorescence mechanism. NGC 6210 is likely to be evolved from a progenitor of more than $3M_{\bullet}$, which had been born near the Galactic plane.

가설 설정

2) velocities based on two Gaussian peaks, ∆P≡∆λ=λ1− λ2, where λ1 is the right peak wavelength and λ2 is the other left peak wavelength.

제안 방법

Using the high dispersion spectral data (0.28Å/pixel) observed with the Hamilton Echelle Spectrograph (HES) at Lick observatory, we investigated the expansion velocities of the shell gas to see whether there is any systematical change in the velocity structure of the expanding shell.

대상 데이터

The spectroscopic observations had been carried out in 1995 July 4 (UT) and 2001 August 28 (UT) using the HES attached at the 3-m Shane telescope at Lick observatory. The whole nebular dimension is about 25''×35''.

이론/모형

Our HES data also allow us to study the kinematics of NGC 6210, which was not possible in the earlier investigations by Kwitter and Henry (1998) and Phillips and Cuesta (1996). Line profiles were analyzed using the IRAF and ESO StarLink/Dipso reduction package. Fig.
