The symbiotic star H 1 - 36 A composite model of line and continuum spectra from radio to ultraviolet
Context. In this paper we analyse the spectra of D-type SS H1-36 within a colliding-wind scenario. Aims. We aim to analyse the properties of this object taking into account the observational data along the whole electromagnetic spectrum, in order to derive a self-consistent picture able to interpret the nature of the system as a whole. Methods. After constraining the relative physical condition...
متن کاملDiscovery in IC 10 of the farthest known symbiotic star ⋆
We report the discovery of the first known symbiotic star in IC10, a starburst galaxy belonging to the Local Group, at a distance of ∼750 kpc. The symbiotic star was identified during a survey of emission-line objects. It shines at V =24.62±0.04, V −RC=2.77±0.05 and RC−IC=2.39±0.02 and suffers from EB−V =0.85±0.05 reddening. The spectrum of the cool component well matches that of solar neighbor...
متن کاملA radio jet in the prototypical symbiotic star Z And ?
As part of a multi-wavelength campaign to observe the 2000–2002 outburst of the prototypical symbiotic star Z Andromedae, we observed this object six times each with the Multi-Element Radio Linked Interferometer Network (MERLIN) and Very Large Array (VLA). The radio flux varied significantly during the course of the optical outburst at all three observation frequencies (1.4, 5, and 15 GHz). A j...
متن کاملHigh Resolution Radio Images of the Symbiotic Star R Aquarii
We present MERLIN radio observations of the nearby symbiotic star R Aquarii at 5 and 1.7 GHz with respective nominal resolutions of 0:04 and 0.13 arcsec, comparable to the resolution of the optical and ultraviolet images obtained with the HST. Comparison with the HST images shows that the radio emission is associated with features observed at optical and UV wavelengths. In particular, this comp...
متن کاملThe Symbiotic Neutron Star Binary Gx 1+4/v2116 Ophiuchi
We present extensive optical, infrared, and X-ray observations of the S-type symbiotic low-mass X-ray binary GX 1+4/V2116 Oph, which consists of a 2-min X-ray pulsar accreting from an M6 III giant. This is the only symbiotic system definitely known to contain a neutron star. The mean observed spectral type of the X-ray-heated mass donor is M5 III. The steady interstellar extinction toward the b...
