Finding substructures in protostellar disks in Ophiuchus
Arnaud Michel, Sarah I. Sadavoy, Patrick D. Sheehan +5
High-resolution, millimeter observations of disks at the protoplanetary stage reveal substructures such as gaps, rings, arcs, spirals, and cavities. While many protoplanetary disks…
A millimeter-multiwavelength continuum study of VLA 1623 West
Arnaud Michel, Sarah I. Sadavoy, Patrick D. Sheehan +2
VLA 1623 West is an ambiguous source that has been described as a shocked cloudlet as well as a protostellar disk. We use deep ALMA 1.3 and 0.87 millimeter observations to constrai…
Bridging the gap between protoplanetary and debris disks: separate evolution of millimeter and micrometer-sized dust
Arnaud Michel, Nienke van der Marel, Brenda Matthews
The connection between the nature of a protoplanetary disk and that of a debris disk is not well understood. Dust evolution, planet formation, and disk dissipation likely play a ro…
Planetary mass-radius relations across the galaxy
A. Michel, J. Haldemann, C. Mordasini +1
Planet formation theory suggests that planet bulk compositions are likely to reflect the chemical abundance ratios of their host star's photosphere. Variations in the abundance of…
