Spectral properties of asteroids in cometary orbits
Aims: In this paper we analyze the spectra of a sample of asteroids in cometary orbits (ACOs) in order to understand the relationship between them, the Jupiter...
Spectral signature of uncombed penumbral magnetic fields
The uncombed penumbral model proposed by Solanki & Montavon (cite{sol93a}) is used to understand some recent observational results found in penumbrae. This...
Spectral signature of uncombed penumbral magnetic fields. Comment
The conservation of magnetic flux demands a magnetic field fine structure as small as 15 km to explain the net circular polarization observed in penumbrae...
Spectral signature of uncombed penumbral magnetic fields. Reply
A combination of two penumbral models similar to those used by Martínez Pillet (2000) is presented. One matches the observed rms fluctuations perfectly while...
Spectro-photometric close pairs in GOODS-S: major and minor companions of intermediate-mass galaxies
Aims: Recent work has shown that major mergers of disc galaxies can only account for 20% of the growth of the galaxy red sequence between z = 1 and z = 0. Our...
Spectro-photometric evolution of elliptical galaxies. II. Models with infall.
In this paper we present new chemo-spectro-photometric models of elliptical galaxies in which infall of primordial gas is allowed to occur. They aim to simulate...
Spectropolarimetric analysis of an active region filament. I. Magnetic and dynamical properties from single component inversions
Aims: The determination of the magnetic filed vector in solar filaments is made possible by interpreting the Hanle and Zeeman effects in suitable chromospheric...
Spectropolarimetric analysis of an active region filament.. II. Evidence of the limitations of a single-component model
Aims: Our aim is to demonstrate the limitations of using a single-component model to study the magnetic field of an active region filament. To do this, we...
