We describe a new method to derive clean, iodine-free spectra directly from observations acquired using high-resolution echelle spectrographs equipped with iodine cells. The main motivation to obtain iodine-free spectra ...

Information collected in the present high resolution study of 104Pd(d,t)103Pd is interpreted within the systematics of the A ~ 100 region. The paper complements data previously presented by the S.Paulo Group, which were ...

High-resolution measurements of low-energy conversion electrons have been performed in odd and odd-odd nuclei with masses around A = 182. The experimental setup, a magnetic spectrograph coupled to a specific tape transport ...

Context. Recent developments in observational techniques and theories revealed the potential significance of magnetic fields for stellar structure, evolution, and circumstellar environment. At present, the distribution of ...

The continuous photometric observations collected by the Kepler satellite over 4 yr provide a wealth of data with an unequalled quantity and quality for the study of stellar evolution of more than 200 000 stars. Moreover, ...

Context. Theories on the origin of magnetic fields in massive stars remain poorly developed, because the properties of their magnetic field as function of stellar parameters could not yet be investigated. Additional ...

Our recent search for the presence of a magnetic field in the bright earlyA-type supergiant HD92207 using FORS2 in spectropolarimetric mode revealed thepresence of a longitudinal magnetic field of the order of a few hundred ...

Context. Solar-analogue stars provide an excellent resource to study the Sun’s evolution, i.e. the changes with time in stellar structure, activity, or rotation for solar-like stars. The unparalleled photometric data from ...
