Due to the present situation and developments related to the corona virus pandemy, we have decided to cancel the Symposium this year and to move it to a similar time of year, i.e. mid to late September or early October 2021. We hope to be able to keep the program largely intact, i.e. stay with the same list of review and invited speakers. We are presently discussing the logistics and possible dates with the conference organizer and the provider of the conference facilities in Puerto Varas. We hope to be able to announce the new dates within the next week or so. Please stay tuned.

The registration page has been closed. People, who have already registered and paid, will get reimbursed. ContactoChile will contact and notify the affected people in due time.

Scope of the conference

The 7th Chile-Cologne-Bonn-Symposium (in series of the former Zermatt-Cologne-Bonn-Symposia) Physics and Chemistry of Star Formation; The Dynamical ISM Across Time and Spatial Scales (mid to late September or early October 2021) continues the series of symposia on the physics and chemistry of the interstellar medium (ISM) which is held on a roughly 5 year cycle since 1988.

Following the long-term tradition of the former Zermatt Symposia on the Interstellar Medium, we will stay with the concept of a broad topical range, addressing all aspects from the large scales in time and space, i.e., the cosmological evolution of galaxies driven by star formation, down to the details of star formation in individual, local regions and to the micro-physics of molecule formation and excitation. The Symposium thus will cover the development of this research field as a whole over the last 5 years in review talks,  and the recent topical results in selected contributed talks.

Sessions / Review and Invited talks

Each Session will allow for approximately  6 contributed talks of 15(+5) min duration. The SOC will select about 45 contributed talks from the submitted abstracts, and will recommend which talks may get accepted as posters. The Symposium will have two Poster Sessions (2 hours each), each with 100 posters, which will also be accessible during the coffee breaks, all through Monday/Tuesday and Thursday/Friday. Thus (almost) every participant will be able to present at least one poster.
