The Astronomical Journal, 2023 Using the GALEX archive, we have discovered extended structures around ten asymptotic giant branch (AGB) stars (out of a total 92 searched) emitting in the far-ultraviolet (FUV) band.

Planetary Evaporation and the Dynamics of Planet Wind/Stellar Wind Bow Shocks [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractWe present initial results of a new campaign of simulations focusing on the interaction of planetary winds with stellar environments using Adaptive Mesh Refinement methods. We have confirmed the results of Stone & Proga (2009) that an azimuthal flow structure is created in the planetary wind due to day/night temperatures differences.

Ram-pressure balance surfaces for an outwardly accelerating stellar wind bow shock [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We study the problem of a stellar wind bowshock (produced by an isotropic wind/plane flowing environment interaction) that lies within the wind acceleration region in the simple, ram-pressure balance approximation. We show that this problem has a simple, approximate analytic solution that produces reasonably accurate results when applied to wind ...

Gamma-ray emission from early-type stars interacting with AGN jets
EPJ Web of Conferences, 2013 We study the interaction of early-type stars with the jets of active galactic nuclei. A bow-shock will form as a consequence of the interaction of the jet with the winds of stars and particles can be accelerated up to relativistic energies in these ...

THE MYSTERIOUS SICKLE OBJECT IN THE CARINA NEBULA: A STELLAR WIND INDUCED BOW SHOCK GRAZING A CLUMP? [PDF]
The Astrophysical Journal, 2013 Optical and near-infrared images of the Carina Nebula show a peculiar arc-shaped feature, which we call the "Sickle", next to the B-type star Trumpler 14 MJ 218. We use multi-wavelength observations to explore and constrain the nature and origin of the nebulosity. Using sub-mm data from APEX/LABOCA as well as Herschel far-infrared maps, we discovered a

Ks- andLp-band polarimetry on stellar and bow-shock sources in the Galactic center [PDF]
Astronomy & Astrophysics, 2013 Infrared observations of the Galactic center (GC) provide a unique opportunity to study stellar and bow-shock polarization effects in a dusty environment. The goals of this work are to present new Ks- and Lp-band polarimetry on an unprecedented number of sources in the central parsec of the GC, thereby expanding our previous results in the H- and Ks ...

OB runaway stars originating in the Vel OB1 association
Astronomy & AstrophysicsContext. OB runaway stars are massive stars moving through interstellar space with a high velocity (up to 200 km s−1). They are produced by dynamical ejections in young massive clusters or by supernova explosions in massive binaries.
