Abstract In A- and late B-type stars, strong magnetic fields are always associated with Ap and Bp chemical peculiarities. However, it is not clear at what point in a star's evolution those peculiarities develop. Strong magnetic fields have been observed in pre-main sequence A and B stars (Herbig Ae and Be stars), and these objects have been proposed to be the progenitors of Ap and Bp stars. However, the photospheric chemical abundances of these magnetic Herbig stars have not been studied… 

Magnetic fields in non-convective regions of stars

Whether the Sun could harbour a magnetic field in its core is discussed, and possible dynamo mechanisms that run on differential rotation rather than convection are looked at.

Chemical abundances of the high-latitude Herbig Ae Star PDS2

The Herbig Ae star PDS2 (CD -53 251) is unusual in several ways. It has a high Galactic latitude, unrelated to any known star-forming region. It is at the cool end of the Herbig Ae sequence, where



Chemical abundances of magnetic and non-magnetic Herbig Ae/Be stars

The photospheres of about 10–20 per cent of main-sequence A-and B-type stars exhibit a wide range of chemical peculiarities, often associated with the presence of a magnetic field. It is not exactly

Magnetic fields and chemical peculiarities of the very young intermediate-mass binary system HD 72106

The recently discovered magnetic Herbig Ae and Be stars may provide qualitatively new information about the formation and evolution of magnetic Ap and Bp stars. We have performed a detailed

A search for strong, ordered magnetic fields in Herbig Ae/Be stars★

The origin of magnetic fields in intermediate- and high-mass stars is fundamentally a mystery. Clues towards solving this basic astrophysical problem can likely be found at the pre-main-sequence

Characterization of the magnetic field of the Herbig Be star HD 200775

The origin of the magnetic fields observed in some intermedia te mass and high mass main sequence stars is still a matter of vigorous debate. The favo ured hypothesis is a fossil field origin, in

Chemical analysis of 24 dusty (pre-)main-sequence stars

We have analysed the chemical photospheric composition of 24 Herbig Ae/Be and Vega-type stars in search for the λ Bootis phenomenon. We present the results of the elemental abundances of the sample

A high-resolution spectropolarimetric survey of Herbig Ae/Be stars – I. Observations and measurements

This is the first in a series of papers in which we describe and report the analysis of a large survey of Herbig Ae/Be stars in circular spectropolarimetry. Using the ESPaDOnS and Narval

A spectroscopic survey for lambda Bootis stars. III. Final results

In the third paper of a series dedicated to the spectroscopic survey for new Bootis stars, we present all new and conrmed members of the group as well as a detailed analysis of the observed sample.

The chemical composition of three Lambda Bootis stars

Abundance analyses are reported for three certain members (Lambda Boo, 29 Cyg, Pi1 Ori) of the class of rapidly rotating, metal-poor A-type stars known as Lambda Bootis stars. Model atmosphere

Particle Transport and the lambda Bootis Phenomenon. I. The Diffusion/Mass-Loss Model Revisited

Recent observational work has cast doubt on the validity of the diffusion-based model originally developed to account for the peculiar characteristics of the λ Bootis stars. Among some of the
