The dance of dust: Investigating young stellar object dipper variability
A. Empey, R. Garcia Lopez, A. Natta +4
The dipper subclass of YSOs are characterised by frequent dips in their light curves. Irregular dippers do not show periodic signatures and have dips accounting for significant pro…
Discovery of an Accretion Burst in a Free-Floating Planetary-Mass Object
V. Almendros-Abad, A. Scholz, B. Damian +7
We report the discovery of a long-lasting burst of disk accretion in Cha J11070768-7626326 (Cha 1107-7626), a young, isolated, 5-10 M object. In spectra taken…
Probing accretion and stellar properties in the Orion Nebula with VLT/X-Shooter
L. Piscarreta, G. Beccari, R. A. B. Claes +6
Multiple photometric studies have reported the presence of seemingly older accreting pre-main sequence stars (PMS) in optical colour-magnitude diagrams (CMDs). We investigate this…
The accretion luminosity of Class I protostars
L. Testi, A. Natta, S. Gozzi +7
The value of the accretion luminosity during the early phases of star formation is a crucial information which helps us understand how stars form, yet it is still very difficult to…
FitteR for Accretion ProPErties of T Tauri stars (FRAPPE): A new approach to use Class III spectra to derive stellar and accretion properties
R. A. B. Claes, J. Campbell-White, C. F. Manara +10
Studies of the stellar and accretion properties of classical T Tauri stars (CTTS) require comparison with photospheric spectral templates. Here we aim at expanding the currently av…
Evolution of the relation between the mass accretion rate and the stellar and disk mass from brown dwarfs to stars
V. Almendros-Abad, C. F. Manara, L. Testi +7
The time evolution of the dependence of the mass accretion rate with the stellar mass and the disk mass represents a fundamental way to understand the evolution of protoplanetary d…
