CIRCUMSTELLAR SHELL FORMATION IN SYMBIOTIC RECURRENT NOVAE [PDF]
The Astrophysical Journal, 2012 We present models of spherically symmetric recurrent nova shells interacting with circumstellar material in a symbiotic system composed of a red giant expelling a wind, and a white dwarf accreting from this material. Recurrent nova eruptions periodically eject material at high velocities ($\gtrsim 10^3$ km/s) into the red giant wind profile, creating a

IR Observations of the Symbiotic Nova HM Sagittae [PDF]
International Astronomical Union Colloquium, 1990 The infrared photometry of the symbiotic nova HM Sge, with a Mira variable as a cool component, shows that since 1983 its mean IR brightness began to decrease from the previous post-outburst level (Figure 1). In 1988 the mean J magnitude was already about 1 mag fainter than it had been until 1983.An analysis of the photometric observations shows that ...

International Astronomical Union Colloquium, 1988 AbstractSymbiotic Novae are composite spectrum variables, whose light history is characterized by a single nova-like outburst. Their behaviour and time evolution is rather similar to that of classical novae, except for the much longer time scale, and the associated physics could be the same.

The Light Curve of the Symbiotic Nova HM Sagittae [PDF]
International Astronomical Union Colloquium, 1990 The light curve of the symbiotic nova HM Sge in 1960–1988 derived from 260 photographic and 243 photoelectric observations (Arkhipova et al. 1989) in presented in Fig. 1.The rate of nova-like brightness increase in 1975 was about 0.04 mag/day. The maximum duration was about 4 years, with brightness oscillations of up to 1 mag.

Spectroscopic Variations of the Symbiotic Nova PU VUL [PDF]
International Astronomical Union Colloquium, 1988 AbstractEvidence for formation and subsequent expansion of an A–F supergiant envelope in the very slow symbiotic nova PU Vul caused by quasiperiodic injections of matter from M giant to the A–F supergiant is given.

The Outburst of Symbiotic Novae [PDF]
Symposium - International Astronomical Union, 1992 We present the basic properties of symbiotic novae, and show how they differ from classical novae. Differences are observationally particularly noticeable in the luminosity curve, the rise of which is much slower, but its return to pre-outburst level takes much longer than in classical novae. Special emphasis is given to the intial phase, for which two

A Mystery in Chamaeleon: Serendipitous Discovery of a Galactic Symbiotic Nova
The Astronomical Journal, 2020 Abstract We present the serendipitous discovery of a low optical-luminosity nova occurring in a D-type symbiotic binary star system in the Milky Way. We lay out the extensive archival data alongside new follow-up observations related to the stellar object CN Cha in the constellation of Chamaeleon.

Bolometric Light Curves of Symbiotic Novae [PDF]
Symposium - International Astronomical Union, 1992 We determine bolometric light curves and total energies radiated away during the outburst of symbiotic novae. Time integrated lower limits to the total energy of 0.9×1046<E[erg] < 7×1046are found. Thus, the output is comparable to, or larger than the total energy production of a classical nova outburst.

Integrating Enterprise Resource Planning (ERP) Systems to Symbiotic Simulation [PDF]
, 2014 Symbiotic simulation is inspired by symbiosis in biology and is defined as a close association between a simulation system and a physical system, which is usually beneficial to at least one of them. Many applications have been proposed in recent years
