A giant solution to the disk mass budget problem of planet formation

Sofia Savvidou

Understanding how dust evolves in protoplanetary disks is crucial to constraining the initial conditions of planet formation. The apparent "mass budget problem", which stems from t…

Simulating the interplay between the snowline pebble flux and ongoing planet formation and migration

Danila Astrakhantsev, Sebastiaan Krijt, Sofia Savvidou +1

Pebble drift plays a central role in modern planet formation models. In this work we carry out planet formation simulations (including pebble accretion and migration) for a range o…

How disc initial conditions sculpt the atmospheric composition of giant planets

Angie Daniela Guzmán Franco, Sofia Savvidou, Bertram Bitsch

Past studies have revealed the dependency of the disc parameters (mass, radius, viscosity, grain fragmentation velocity, dust-to-gas ratio) on the formation of giant planets, where…

There is no disk mass budget problem of planet formation

Sofia Savvidou, Bertram Bitsch

The inferred dust masses from Class II protoplanetary disk observations are lower than or equal to the masses of the observed exoplanet systems. This poses the question of how plan…

How to make giant planets via pebble accretion

Sofia Savvidou, Bertram Bitsch

Planet formation is directly linked to the birthing environment that protoplanetary disks provide. The disk properties determine whether a giant planet will form and how it evolves…

EDEN Survey: Small Transiting Planet Detection Limits and Constraints on the Occurrence Rates for Late M Dwarfs within 15 pc

Jeremy Dietrich, Dániel Apai, Martin Schlecker +29

Earth-sized exoplanets that transit nearby, late spectral type red dwarfs will be prime targets for atmospheric characterization in the coming decade. Such systems, however, are di…

The water-ice line as a birthplace of planets: Implications of a species-dependent dust fragmentation threshold

Jonas Müller, Sofia Savvidou, Bertram Bitsch

The thermodynamic structure of protoplanetary discs is determined by dust opacities, which depend on the size of the dust grains and their chemical composition. In the inner region…

The growth of super-Earths: the importance of a self-consistent treatment of disc structures and pebble accretion

Sofia Savvidou, Bertram Bitsch

The conditions in the protoplanetary disc are determinant for the various planet formation mechanisms. We present a framework which combines self-consistent disc structures with th…

Influence of grain sizes and composition on the contraction rates of planetary envelopes and on planetary migration

Bertram Bitsch, Sofia Savvidou

A crucial phase during planetary growth is the migration when the planetary core has been assembled, but the planet did not open a deep gap yet. During this phase the planet is sub…

Influence of grain growth on the thermal structure of protoplanetary discs

Sofia Savvidou, Bertram Bitsch, Michiel Lambrechts

The thermal structure of a protoplanetary disc is regulated by the opacity that dust grains provide. However, previous works have often considered simplified prescriptions for the…

Finsler-Randers Cosmology: dynamical analysis and growth of matter perturbations

G. Papagiannopoulos, S. Basilakos, A. Paliathanasis +2

We study for the first time the dynamical properties and the growth index of linear matter perturbations of the Finsler-Randers (FR) cosmological model, for which we consider that…
