An interferometric mid-infrared study of the eruptive star binary Z CMa with MATISSE/VLTI. I. Imaging the protoplanetary disks during the 2023 outburst

F. Lykou, J. Varga, F. Cruz-Saénz de Miera +14

The mid-infrared (MIR) emitting regions of the individual protoplanetary disks in the binary system Z CMa are resolved by MATISSE/VLTI. The observations were obtained during a sere…

Time-resolved protoplanetary disk physics in DQ Tau with JWST

Á. Kóspál, P. Ábrahám, V. V. Akimkin +17

Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…

T CrA has a companion: First direct detection of T CrA B with VLTI/MATISSE

J. Varga, A. Matter, F. Millour +21

T CrA is a Herbig Ae-type young star in a complex circumstellar environment; it includes a circumstellar disk, accretion streamers, jets, and outflows. It has long been suspected t…

Mid-infrared evidence for iron-rich dust in the multi-ringed inner disk of HD 144432

J. Varga, L. B. F. M. Waters, M. Hogerheijde +40

Context. Rocky planets form by the concentration of solid particles in the inner few au regions of planet-forming disks. Their chemical composition reflects the materials in the di…

The bright black hole X-ray binary 4U 1543--47 during 2021 outburst: a thick accretion disk inflated by high luminosity

S. J. Zhao, L. Tao, P. P. Li +17

The black hole X-ray binary source 4U 1543--47 experienced a super-Eddington outburst in 2021, reaching a peak flux of up to …

The disk of the eruptive protostar V900 Mon; a MATISSE/VLTI and MUSE/VLT perspective

F. Lykou, P. Ábrahám, F. Cruz-Sáenz de Miera +8

In this work, we study the silicate dust content in the disk of one of the youngest eruptive stars, V900 Mon, at the highest angular resolution probing down to the inner 10 au of s…

Spectral evolution and radial dust transport in the prototype young eruptive system EX Lup

Péter Ábrahám, Lei Chen, Ágnes Kóspál +7

EX Lup is the prototype of a class of pre-main sequence eruptive stars defined by their repetitive outbursts lasting several months. In 2008 January-September EX Lup underwent its…

Monte-Carlo radiative transfer simulation of the circumstellar disk of the Herbig Ae star HD 144432

L. Chen, A. Kreplin, G. Weigelt +6

Studies of pre-transitional disks, with a gap region between the inner infrared-emitting region and the outer disk, are important to improving our understanding of disk evolution a…
