Introduction

We are pleased to announce the international workshop
“Comet formation paradigm after Rosetta. What is the hallmark of cometary nuclei formation in protoplanetary discs inherited from Rosetta?”
that will be held from June 19 to 23, 2017 in Sofia, Bulgaria. The workshop is organized by the Institute for Space Astrophysics and Planetology (IAPS), National Institute for Astrophysics (INAF), Italy, the Institute of Astronomy and National Astronomical Observatory(IANAO), Bulgarian Academy of Sciences (BAS), and is partially funded by Europlanet 2020 Research Infrastructure(RI).
This workshop aims to gather the scientific community interested in various aspects of cometary science together with experts in planetary formation. The main focus will be to discuss the state-of-the-art cometary nuclei formation paradigm taking into account the recent information coming from observations, laboratory investigations and modelling results, and identifying new scientific goals for the post-Rosetta era.
The workshop is one of the main post-Rosetta scientific forums in 2017.
The organizing committees look forward to seeing you in Sofia and making your visit fruitful and enjoyable!

Rationale

The Rosetta findings have already brought cometary science to a new level. The interpretation of the acquired data is driving a large scale revision of our understanding of comet formation and is also leading us to reconsider some of the established concepts related to the formation and evolution of the Solar System. Moreover, this has broader implications as comet composition and formation encompasses astrophysics, astrochemistry and astrobiology. This workshop aims to gather the scientific community interested in various aspects of cometary science together with experts in planetary formation. The main focus will be to discuss the state-of-the-art cometary nuclei formation paradigm taking into account the recent information coming from observation, laboratory investigations and modelling results, and identifying new scientific goals for the post-Rosetta era. The meeting will provide a unique and timely forum for a discussion on our understanding of the role of the comets in the Solar System formation and evolution. The format will consist of plenary sessions with contributed and invited presentations.

Scientific Topics

A temporal evolution of a Solar System:
  1. From the pre-solar cloud to the dust and icy grains:
    1. Cometary ices in the protoplanetary discs
    2. Dust grains formation and growth
    3. Formation of the Solar System
    4. Observations and modelling
  2. Mass transport and mixing within the Solar System
    1. Radial mixing
    2. Planet migration
    3. Observations and modelling
  3. Planetesimal formation/ from planetesimals to comets evolution
    1. Collisional and dynamical evolution
    2. Streaming instabilities
    3. Rubble piles
    4. Comets formation
    5. Formation of the comets reservoirs
