High Resolution Parameter Study of the Vertical Shear Instability II: Dependence on temperature gradient and cooling time
Natascha Manger, Thomas Pfeil, Hubert Klahr
A certain appeal to the alpha model for turbulence and related viscosity in accretion disks was that one scales the Reynolds stresses simply on the thermal pressure, assuming that…
A multiwavelength analysis of the spiral arms in the protoplanetary disk around WaOph 6
S. B. Brown-Sevilla, M. Keppler, M. Barraza-Alfaro +23
[Full abstract in the paper] In recent years, protoplanetary disks with spiral structures have been detected in scattered light, millimeter continuum, and CO gas emission. The mech…
Resilience of Planetesimal Formation in Weakly-Reinforced Pressure Bumps
Daniel Carrera, Andrew Thomas, Jacob B. Simon +3
The discovery that axisymmetric dust rings are ubiquitous in protoplanetary disks has provoked a flurry of research on the role of pressure bumps in planet formation. High-resoluti…
The CARMENES search for exoplanets around M dwarfs -- Planet occurrence rates from a subsample of 71 stars
S. Sabotta, M. Schlecker, P. Chaturvedi +25
The CARMENES exoplanet survey of M dwarfs has obtained more than 18 000 spectra of 329 nearby M dwarfs over the past five years as part of its guaranteed time observations (GTO) pr…
The New Generation Planetary Population Synthesis (NGPPS). IV. Planetary systems around low-mass stars
Remo Burn, Martin Schlecker, Christoph Mordasini +5
Previous work concerning planet formation around low-mass stars has often been limited to large planets and individual systems. As current surveys routinely detect planets down to…
The New Generation Planetary Population Synthesis (NGPPS). V. Predetermination of planet types in global core accretion models
M. Schlecker, D. Pham, R. Burn +6
State-of-the-art planet formation models are now capable of accounting for the full spectrum of known planet types. This comes at the cost of increasing complexity of the models, w…
