HD 100546 itself is a 位 Boo篓tis star, with solar abundances of C and O but a strong depletion of rock- forming elements. In the gas of the T Tauri disk TW Hya, both C and O are strongly underabundant, with [C]/[H]... M Kama,S Bruderer,EF Van Dishoeck,... - 《Astronomy...

The star HD 100546 (B9Vne) is a so-called 'isolated Herbig Ae/Be star': its strong infrared excess and circumstellar HI emission argue for a young age, but it no longer occurs inside a star-forming region, so that it can be considered a transition object between the youngest, embedded...
We present the first multi-wavelength, high-contrast imaging study confirming the protoplanet embedded in the disk around the Herbig Ae/Be star HD 100546. The object is detected at L' (similar to 3.8 mu m) and M' (similar to 4.8 mu m), but not at K-s (similar to 2.1 mu m), ...
The inner 100 AU of HD 100546 is studied via far-ultraviolet long-slit spectroscopy with the Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS). The star is surrounded by reflection nebulosity, which can be traced 100 AU in the continuum, and by emission from H I Lyα, N ...
FUSE Observations of the Peculiar Hot SDO Star MCT 0019-2441 As part of an extensive study aimed at mapping the photospheric abundance patterns of a dozen chemical species with T eff in hot B and OB subdwarfs, we present here our preliminary results for the star MCT 0019-2441. This star ...
