ALMA detections of circumstellar disks in the giant Hii region M17. Probing the intermediate- to high-mass pre-main-sequence population
J. Poorta, M. Hogerheijde, A. de Koter +8
Our current understanding is that intermediate- to high-mass stars form in a way similar to low-mass stars, that is, through disk accretion. However, the physical conditions that p…
Properties of intermediate- to high-mass stars in the young cluster M17 -- Characterizing the (pre-)zero-age main sequence
Frank Backs, S. A. Brands, M. C. RamÃrez-Tannus +5
The outcome of the formation of massive stars is an important anchor point in their evolution. It provides insight into the physics of the assembly process, and sets the conditions…
The spectroscopic binary fraction of the young stellar cluster M17
M. C. RamÃrez-Tannus, A. R. Derkink, F. Backs +5
Significant progress has been made toward understanding the formation of massive (M) binaries in close orbits. For example, the detection of a very low velocity d…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): PDS 111, an old T Tauri star with a young-looking disk
Annelotte Derkink, Christian Ginski, Paola Pinilla +20
The interplay between T Tauri stars and their circumstellar disks, and how this impacts the onset of planet formation has yet to be established. We studied a seemingly old T Tauri…
Exploring the directly imaged HD 1160 system through spectroscopic characterization and high-cadence variability monitoring
Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone +15
The time variability and spectra of directly imaged companions provide insight into their physical properties and atmospheric dynamics. We present follow-up R~40 spectrophotometric…
