At OAC we are engaged in
a series of activities involving photoelectric photometry of variable
stars. Many of these activities are still working in progress, so
here we don't deal with them.
2013 = V339 DEL was discovered around mid August 2013 by the japanese
At OAC we decided to include V339 DEL among the targets to be photoelectrically
monitored. Actually V339 DEL was monitored both photoelectrically
and spectroscopically at OAC; in fact this target was included in
our C.A.T.S. project which stands for Capannori Astronomical Transients
Survey. You can find more about C.A.T.S. project in the following
link (CCD Photometry and Imagery).
A couple of days after the discovery, we made our first photoelectric
photometry and CCD spectrography of V339 DEL.
In the aftermath we monitored the photometric and spectroscopic
developement of V339 DEL. Some preliminary results of this monitoring
are listed in the following two papers published on line:
M. M. M.,Pasquini M., Gambogi S., Cavalletti G., 2013 ATel.5313
M. M. M.,Pasquini M. 2013 ATel.5295
In ATel 5295
we were the first in the world to claim the presence of the NIR
neutral oxygen triplet at 777.4 nm. Moreover we were among the first
to claim the presence of strong P-Cygni profiles of Hydrogen, Fe
II, and various other elements. We were also the first to publish
R band photoelectric photometry of this nova.
Finally in ATel 5313 we were the first in the world to publish an
estimate of the distance of V339 DEL.
