Abstract
We present here the most recent abundance analysis of this Herbig Ae system based on high-resolution UVES and HARPS spectra and the results of our magnetic field measurements using high-resolution spectra obtained with HARPSpol.
Highlights
HD 104237 (DX Cha) is the optically brightest of the young Herbig Ae stars
The SB2 system was studied by Böhm, et al (2004) who found a 19.86 day period
Atmospheric parameters for the primary star were derived from the wings of Hδ, and the ionization equilibrium, Fe
Summary
HD 104237 (DX Cha) is the optically brightest of the young Herbig Ae stars. The SB2 system was studied by Böhm, et al (2004) who found a 19.86 day period. The binary, and several close companions described by Grady, et al (2004) belong to the ǫ Cha association, estimated to be 3 to 5 Myr old. Fang et al (2013) showed that the SED shows strong emissions at wavelengths beyond ca. 2μm, indicating a hot, optically thick inner disk. The SED is more like that of a flattened disk model than to a flaring disk
