Spectroscopic observations of novae V1065 CEN and V1280 SCO using 45 cm cassegrain telescope at Arthur C Clarke Institute
The spectroscopic observations of two novae namely V1065 CEN and V1280 SCO were made by 45 cm Cassegrain telescope in high resolution ($\lambda/\delta\lambda$=22000) at H$\alpha$ (6563 \r{A}) region. V1065 CEN is He/N-type spectra which characterize a broad (Gaussian FWHM 49 \r{A}), saddle shaped an...

He/N-type spectra which characterize a broad (Gaussian FWHM 49 \r{A}), saddle
shaped and asymmetric H$\alpha$ emission line without prominent P-Cyg
absorption component. Completely different H$\alpha$ profile of V1280 SCO shows
prominent P-Cyg absorption and narrow emission line (Gaussian FWHM 26 \r{A})
which can be classified as Fe II type nova. The expansion velocities of these
two systems measured from the minima of the P-Cyg profiles are close to 2300
km/s for V1065 CEN, and 716 km/s for V1280 SCO. Based on the photometric
analysis, the Nova V1065 CEN can be classified as fast (11$ |
