Nova Aql 2010 (= V1723 Aql)



"Update of spectra"
(2010 October 18 by A. Arai)

We update our spectra of V1723 Aql.


"Update of spectra"
(2010 September 25 by A. Arai)

We update our spectra of V1723 Aql. We noticed that the [O I] at 6300A shows a flat-top profile on September 25. Furthermore, we found that Ha emission showed an excess in the blue wing. This sugges that the aspherical outflow would exist.


"Update of spectra"
(2010 September 17 by A. Arai)

We update our spectra of V1723 Aql. The contribution of the continuum light is decreasing.


"Update of spectra"
(2010 September 15 by A. Arai)

We update our spectra of Nova Aql 2010. The Ha emission line is gradually growing with time keeping a symmetric profile. No significant changes of line profiles and the expansion velocity estimated from the FWHM of the Ha (around 1500km/s) are observed in the early 3 days. These results indicates that the ejected gas is spherically expanding with an constant velocity from the central white dwarf.




"Spectroscopy of Nova Aql 2010"

(2010 September 12 by A.Arai)

The figure shows our spectrum (R~500) of Nova Aql 2010 (IAUC 9167) obtained on Sep. 11.597. We obtained this spectrum using "LOSA/F2 (Low-resolution Optical Spectrograph for Araki with F/2)" attached on the 1.3m ARAKI telescope at Koyam Astronomical Observatory(KAO), Kyoto Sangyo University, Japan. The object shows broad H-alpha and O I (7774A) emission lines with a highly reddened continuum. FWHM of these lines are 1200--1500 km/s.
