We study radiative transfer through a weakly polarizing medium, i.e., a medium in which the degree of polarization of the absorbed, retarded, and emitted light...
Radiative Transfer Modeling of the Enigmatic Scattering Polarization in the Solar Na I D1 Line
The modeling of the peculiar scattering polarization signals observed in some diagnostically important solar resonance lines requires the consideration of the...
We present a set of face-on models of the radiative transfer of stellar light in exponential discs, taking into account absorption and multiple scattering...
Radii, masses, and transit-timing variations of the three-planet system orbiting the naked-eye star TOI-396
Context. TOI-396 is an F6 V bright naked-eye star (V ≈ 6.4) orbited by three small (R p ≈ 2 R ⊕) transiting planets discovered thanks to space-based photometry...
Radio and infrared structures of type I post-main sequence nebulae
High-resolution VLA radio mapping at 1.46, 4.84, and 15.0 GHz is presented together with NIR J,H,K,L, and M mapping and photometry of a broad range of type I...
Radio and Optical Monitoring of 3C 66A during an extended outburst. II. 1995-1997
We present new monitoring observations of the BL Lac object 3C66A, taken between the years 1995-1997. During this period the object was always observed in an...
Radio continuum and far-infrared observations of low surface brightness galaxies
We present Very Large Array (VLA) radio continuum and Infrared Astronomy Satellite (IRAS) far-infrared (FIR) observations of 16 low luminosity galaxies of...
Radio counterparts of unidentified EGRET gamma-ray sources.
We present one new radio identification and one confirmation of two high-latitude gamma-ray sources detected by CGRO-EGRET, based on flux density measurements...
