Spirals and clumps in V960 Mon: signs of planet formation via gravitational instability around an FU Ori star?
P. Weber, S. Pérez, A. Zurlo +11
The formation of giant planets has traditionally been divided into two pathways: core accretion and gravitational instability. However, in recent years, gravitational instability h…
Inner edges of planetesimal belts: collisionally eroded or truncated?
Amaia Imaz Blanco, Sebastian Marino, Luca Matrà +9
The radial structure of debris discs can encode important information about their dynamical and collisional history. In this paper we present a 3-phase analytical model to analyse…
The clumpy structure of Eridani's debris disc revisited by ALMA
Mark Booth, Tim D. Pearce, Alexander V. Krivov +8
Eridani is the closest star to our Sun known to host a debris disc. Prior observations in the (sub-)millimetre regime have potentially detected clumpy structure in the disc and…
The ALMA view of MP Mus (PDS 66): a protoplanetary disk with no visible gaps down to 4 au scales
Á. Ribas, E. Macías, P. Weber +12
We present ALMA multiwavelength observations of the protoplanetary disk around the nearby (d100 pc) young solar analog MP Mus (PDS 66). These observations at 0.89 mm, 1.3 mm,…
Has the dust clump in the debris disk of Beta Pictoris moved?
Yinuo Han, Mark C. Wyatt, William R. F. Dent
The edge-on debris disk of the nearby young star Beta Pictoris shows an unusual brightness asymmetry in the form of a clump. The clump has been detected in both the mid-IR and CO a…
