A complete Herbig disk mass survey in Orion
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +3
Disks around intermediate mass stars called Herbig disks are the formation sites of giant exoplanets. Obtaining a complete inventory of these disks will therefore give insights int…
A dichotomy in group II Herbig disks: ALMA gas disk height measurements show both shadowed large vertically extended disks and compact flat disks
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +1
Herbig stars can be classified into group I and group II depending on the shape of the far-IR excess from the spectral energy distribution. This separation may be evolutionary and…
Iterative Angular Differential Imaging (IADI): An exploration of recovering disk structures in scattered light with an iterative ADI approach
L. M. Stapper, C. Ginski
Distinguishing signal of young gas rich circumstellar disks from stellar signal in near infrared light is a difficult task. Current techniques such as Angular Differential Imaging…
Constraining the gas mass of Herbig disks using CO isotopologues
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +7
The total disk mass sets the formation potential for exoplanets. Carbon-monoxide (CO) has been used as a gas mass tracer in T Tauri disks, but was found to be less abundant than ex…
MINDS survey of silicates in T Tauri disks: Correlation between dust and gas
J. Varga, Th. Henning, L. B. F. M. Waters +20
Context. Silicates are key constituents of planet-forming disks and major building blocks of rocky planets. Mid-infrared spectral features of micron-sized silicate grains trace gra…
Intermediate mass T Tauri disk masses and a comparison to their Herbig disk descendants
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +3
The precursors of Herbig stars are called Intermediate Mass T Tauri (IMTT) stars, which have spectral types later than F, but stellar masses between 1.5 and 5 M_\odot, and will eve…
