Observations of circumstellar disks [PDF]
Proceedings of the International Astronomical Union, 2010 In this review I will present recent results obtained between 2005, which was the last “Be-stars” meeting in Sapporo, and 2010, on the observations of circumstellar disks around active hot stars.

Modelling and interpretation of SEDs*
EPJ Web of Conferences, 2015 Circumstellar disks are mostly detected by larger continuum fluxes in the infrared to mm spectral regions as compared to naked stars (a flux excess).

Observations of circumstellar disks in scattered light with SPHERE at the VLT
Comptes Rendus. Physique, 2023 The technological developments initiated in the early 21$^{\rm st}$ century have led to the implementation of “planet finders” instruments on 8-m class telescopes which are in operation since 2014-2015. Such facilities are at the inception of significant

Extending the ALMA Census of Circumstellar Disks in the Upper Scorpius OB Association
The Astrophysical JournalWe present Atacama Large Millimeter/submillimeter Array (ALMA) Band 7 continuum (340 GHz) and carbon monoxide (CO) J = 3–2 observations for an extended sample of disks in the Upper Scorpius OB Association (Upper Sco, age ∼10 Myr).

Magnetic fields in circumstellar disks
, 2017 Context. Recent high angular resolution polarimetric continuum observations of circumstellar disks provide new insights into their magnetic field. However, direct constraints are limited to the plane-of-sky component of the magnetic field.

MIRI MRS Observations of β Pictoris. I. The Inner Dust, the Planet, and the Gas
The Astrophysical JournalWe present JWST MIRI Medium Resolution Spectrograph (MRS) observations of the β Pictoris system. We detect an infrared excess from the central unresolved point source from 5 to 7.5 μ m which is indicative of dust within the inner ∼7 au of the system.

Vertical Structure of Gas and Dust in Four Debris Disks
The Astrophysical JournalWe present high-spectral-resolution M -band spectra from iSHELL on NASA’s Infrared Telescope Facility along the line of sight to the debris disk host star HD 32297. We also present a Gemini Planet Imager H -band polarimetric image of the HD 131488 debris

Takeout and Delivery: Erasing the Dusty Signature of Late-stage Terrestrial Planet Formation
The Astrophysical Journal, 2023 The formation of planets like Earth is expected to conclude with a series of late-stage giant impacts that generate warm dusty debris, the most anticipated visible signpost of terrestrial planet formation in progress.

Scattered Radiation of Protoplanetary Disks
Universe, 2022 Scattered radiation of circumstellar (CS) dust plays an important role in the physics of young stars. Its observational manifestations are various but more often they are connected with the appearance of intrinsic polarization in young stars and their CS
