We present an overview and first results from a M-band spectroscopic survey of planet-
forming disks performed with iSHELL on the Infrared Telescope Facility, using two slits that …

We investigate the bright CO fundamental emission in the central regions of five protostars in
their primary mass assembly phase using new observations from JWST's Near-Infrared …

Context. We exploit the increased sensitivity of the recently installed adaptive optics SOUL at
the LBT to obtain new high-spatial-resolution near-infrared images of the massive young …

Context. The young massive-star-forming region M17 contains optically visible massive pre-
main-sequence stars that are surrounded by circumstellar disks. Such disks are expected to …

Context. Young stellar objects are thought to accrete material from their circumstellar disks
through their strong stellar magnetospheres. Aims. We aim to directly probe the …

Context. Circumstellar discs are essential for the formation of high mass stars, while
multiplicity, and in particular binarity, appears to be an inevitable outcome, as the vast …

Context. Recently much progress has been made in probing the embedded stages of
massive star formation, pointing to formation scenarios that are reminiscent of a scaled-up …

Context. The formation and evolution of planetary systems impact the evolution of the
primordial accretion disk in its dust and gas content. HD 141569 is a peculiar object in this …

We present the results of the spectral line-shape study of the first measurement of the
extremely weak (7–0) band of the 12 C 16 O molecule. Measurements were done with a …

Context. Protoplanetary disks in dense, massive star-forming regions are strongly affected
by their environment. How this environmental impact changes over time is an important …
