NIKA2 observations of dust grain evolution from star-forming filament to T-Tauri disk: Preliminary results from NIKA2 observations of the Taurus B211/B213 filament [PDF]
EPJ Web of Conferences, 2023 To understand the evolution of dust properties in molecular clouds in the course of the star formation process, we constrain the changes in the dust emissivity index from star-forming filaments to prestellar and protostellar cores to T Tauri stars. Using

Dust Disks Around Young Stellar Objects [PDF]
Journal of Astronomy and Space Sciences, 2016 To reproduce the spectral energy distributions (SEDs) of young stellar objects (YSOs), we perform radiative transfer model calculations for the circumstellar dust disks with various shapes and many dust species.

Discovery of a New Molecular Bubble–Outflow Structure in the Taurus B18 Cloud
The Astrophysical Journal, 2023 Star formation can produce bubbles and outflows, as a result of stellar feedback. Outflows and bubbles inject momentum and energy into the surrounding interstellar medium, and so are related to the overall energy balance of the molecular cloud. Molecular

Twenty-five Years of Accretion onto the Classical T Tauri Star TW Hya
The Astrophysical Journal, 2023 Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of the mass accretion rate onto TW Hya, the nearest accreting solar-mass ...

Tracing episodic accretion with NOEMA: FU Orionis-type stars and their millimeter environment [PDF]
EPJ Web of Conferences, 2022 The earliest phases of star formation are characterised by intense mass accretion from the circumstellar disk to the central star. One group of lowmass young stellar objects, FU Orionis-type stars (FUors) exhibit accretion rate peaks accompanied by ...

Determining Dust Properties in Protoplanetary Disks: SED-derived Masses and Settling with ALMA
The Astrophysical Journal, 2023 We present spectral energy distribution (SED) modeling of 338 disks around T Tauri stars from 11 star-forming regions, ranging from ∼0.5 to 10 Myr old.
