Reconstructing Historical Light Curves of Symbiotic Stars and Novae

open access: yesOpen Astronomy, 2012
We reconstructed photometric histories of symbiotic stars and novae from direct inspection and measurement of photographic plates preserved at historical archives.

Infrared Spectroscopy of Symbiotic Stars. IX. D-Type Symbiotic Novae [PDF]

open access: yesAstrophysical Journal, 2013
Time-series spectra of the near-infrared 1.6 {mu}m region have been obtained for five of the six known D-type symbiotic novae. The spectra map the pulsation kinematics of the Mira component in the Mira-white dwarf binary system and provide the center-of-mass velocity for the Mira.

Eruptive Novae in Symbiotic Systems [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACTWe conduct numerical simulations of multiple nova eruptions in detached, widely separated symbiotic systems that include an asymptotic giant branch (AGB) companion to investigate the impact of white dwarf (WD) mass and binary separation on the evolution of the system.

High Energy Emission of Symbiotic Recurrent Novae: RS Oph and V407 Cyg

open access: yesOpen Astronomy, 2012
Recurrent novae occurring in symbiotic binaries are candidate sources of high energy photons, reaching GeV energies. Such emission is a consequence of particle acceleration leading to pion production.

The Structure of the Envelopes of Symbiotic Novae [PDF]

open access: yesLecture Notes in Physics, 1990
Symbiotic novae are composite spectrum stars whose light history is characterized by one single major outburst. At high resolution their optical and UV spectra are very rich of emission lines belonging to a wide ionization range. Generally one can identify both narrow and broad line systems.

MULTI-FREQUENCY STUDY OF SYMBIOTIC NOVAE

open access: yesOdessa Astronomical Publications, 2017
Symbiotic novae are subclass of symbiotic stars - interacting binaries with wide orbits, whose photometric history is characterized by a single nova- like outburst lasting decades and caused by a thermonuclear runaway on the surface of a wind accreting ...

Hydrodynamic Studies of the Evolution of Recurrent, Symbiotic and Dwarf Novae: The White Dwarf Components Are Growing in Mass

open access: yesOpen Astronomy, 2012
Symbiotic binaries are systems containing white dwarfs (WDs) and red giants. Symbiotic novae are those systems in which thermonuclear eruptions occur on the WD components.

Near-Infrared and Ultraviolet Spectrophotometry of Symbiotic Novae [PDF]

open access: yesAstrophysical Journal, Supplement Series, 1999
ABSTRACTIn this paper we present an atlas of near-infrared spectrophotometry of symbiotic novae and reportresults from nearly contemporaneous IUE observations. The data cover RT Ser, AG Peg, V1016 Cyg,V1329 Cyg, HM Sge, and Pu Vul, most of the known symbiotic novae that are observable from thenorthern hemisphere.

The outbursts of symbiotic novae [PDF]

open access: yesThe Astrophysical Journal, 1983
We discuss possible conditions under which thermonuclear burning episodes in the hydrogen-rich envelopes of accreting white dwarfs give rise to outbursts similar in nature to those observed in the symbiotic stars AG Peg, RT Ser, RR Tel, AS 239, V1016 Cyg, V1329 Cyg, and HM Sge.

Theoretical Light-curve Models of the Symbiotic Nova CN Cha—Optical Flat Peak for 3 Yr

open access: yesThe Astrophysical Journal, 2023
CN Cha is a slow symbiotic nova characterized by a 3 yr long optical flat peak followed by a rapid decline. We present theoretical light curves for CN Cha, based on hydrostatic approximation, and estimate the white-dwarf (WD) mass to be ∼0.6 M _☉ for a ...
