On the formation of our solar system and many other protoplanetary systems observed by ALMA and SPHERE

  author={Dimitris M. Christodoulou and Demosthenes Kazanas},
  journal={arXiv: Earth and Planetary Astrophysics},
In view of the many recent observations conducted by ALMA and SPHERE, it is becoming clear that protoplanetary disks form planets in narrow annular gaps at various distances from the central protostars before these protostars are actually fully formed and the gaseous disks have concluded their accretion/dispersal processes. This is in marked contrast to the many multi-planet exoplanetary systems that do not conform to this pristine picture. This major discrepancy calls for an explanation. We…

Protoplanetary Disk Rings and Gaps across Ages and Luminosities

Since the discovery of the multiring structure of the HL Tau disk, ALMA data suggest that the dust continuum emission of many, if not all, protoplanetary disks consists of rings and gaps, no matter

Solar System Formation in the Context of Extra-Solar Planets

Exoplanet surveys have confirmed one of humanity's (and all teenagers') worst fears: we are weird. If our Solar System were observed with present-day Earth technology -- to put our system and

High-resolution ALMA Observations of HD 100546: Asymmetric Circumstellar Ring and Circumplanetary Disk Upper Limits

We present long-baseline Atacama Large Millimeter/submillimeter Array observations of the 870 μm dust continuum emission and CO (3–2) from the protoplanetary disk around the Herbig Ae/Be star HD

Gas density perturbations induced by forming planet(s) in the AS 209 protoplanetary disk as seen with ALMA

The formation of planets occurs within protoplanetary disks surrounding young stars, resulting in perturbation of the gas and dust surface densities. Here, we report the first evidence of spatially

Exact Solutions of the Isothermal Lane--Emden Equation with Rotation and Implications for the Formation of Planets and Satellites

We have derived exact solutions of the isothermal Lane--Emden equation with and without rotation in a cylindrical geometry. The corresponding hydrostatic equilibria are most relevant to the dynamics

Handbook of Exoplanets

This state-of-the-art reference work includes over 15 sections dealing with all aspects of exoplanets and exobiology research, including historic aspects, the Solar System as a template, objects at

New stationary solutions of the cubic nonlinear Schrödinger equations for Bose-Einstein condensates

We have previously formulated a simple criterion for deducing the intervals of oscillations in the solutions of second-order linear homogeneous differential equations. In this work, we extend
