The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Complete Size Distributions for the 100 Brightest Disks Across Multiplicity and SED Classes
Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova +16
The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d 140-200 pc). We present the complete continuu…
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…
Primordial or Secondary? Testing models of debris disk gas with ALMA
Gianni Cataldi, Yuri Aikawa, Kazunari Iwasaki +13
The origin and evolution of gas in debris disks is still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed. So far, obs…
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 Doppler-flip in HD100546 as a disk eruption: the elephant in the room of kinematic protoplanet searches
Simon Casassus, Miguel Carcamo, Antonio Hales +2
The interpretation of molecular-line data in terms of hydro dynamical simulations of planet-disk interactions fosters new hopes for the indirect detection of protoplanets. In a mod…
High-resolution ALMA observations of V4046Sgr: a circumbinary disc with a thin ring
Rafael Martinez-Brunner, Simon Casassus, Sebastián Pérez +8
The nearby V4046 Sgr spectroscopic binary hosts a gas-rich disc known for its wide cavity and dusty ring. We present high resolution (20 mas or 1.4 au) ALMA observations of t…
