Modeling the bow-shock of Ophiuchi
(Livraria da Física, 2013)
Runaway masive stars are O- and B-type stars with large peculiar veloci- ties. Runaway OB stars can produce stellar bowshocks in the surrounding interstellar medium. Bowshocks develop as arc-shaped structures while the ...
New parametric decays of proton beam-plasma electromagnetic waves
(Blackwell Publishing Ltd, 2002)
Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...
Multi-zone non-thermal radiative model for stellar bowshocks
(EDP Sciences, 2018-09)
Context. Runaway stars produce bowshocks that are usually observed at infrared (IR) wavelengths. Non-thermal radio emission has been detected so far only from the bowshock of BD+43°3654, whereas the detection of non-thermal ...
Is the bowshock of the runaway massive star HD 195592 a Fermi source?
(Edp Sciences, 2013-01)
Context. HD 195592 is an O-type super-giant star, known as a well-established runaway. Recently, a Fermi gamma-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported.

Possible Association of Two Stellar Bowshocks with Unidentified Fermi Sources
(IOP Publishing, 2018-07)
The bowshocks of runaway stars had been theoretically proposed as gamma-ray sources. However, this hypothesis has not been confirmed by observations to date. In this paper, we present two runaway stars (λ Cep and LS 2355) ...
Energetics of nearby stellar bow shocks
(Paideia, 2012)
The latest survey of stellar bow shocks (Peri et al. 2012, A&A, 538, 108) lists 28 candidates detected at IR wavelengths, associated with massive, early-type stars up to 3 kpc, along with the geometrical parameters of the ...
Analysis of the spectral energy distribution from a runaway star bow shock
(Universidad Nacional Autónoma de México, 2011)
The bow shock produced by the high-mass runaway star BD +43° 3654 (Comerón & Pasquali 2007) has been detected as a non-thermal radio source (S_ν ∝ ν^{-α}, <α>=0.5) and it is the first one of that type ever observed (Benaglia ...
