Star Formation: From Clouds to Discs
A Tribute to the Career of Lee Hartmann
Hosted by the Dublin Institute for Advanced Studies
17th - 20th August 2020, Grand Hotel, Malahide, Ireland


The Dublin Institute for Advanced Studies is delighted to host this conference in August 2020 at the Grand Hotel in Malahide, just north of Dublin. This conference's purpose is to bring together experts within the star formation community in tribute to the career of Lee Hartmann.

"... bringing the star formation community together ..."

Titled 'From Clouds to Discs', our covered range of topics spans multiple orders of magnitude in scale and a variety of phenomena, from the birth conditions of young stars, to their accretion discs and back out to examine their feedback upon their environment.

Scientific Rationale

Star formation involves many physical processes, scales, and different types of objects, the origin of which are subject to intense debate. How do molecular clouds form and how do they evolve? What are the key processes that define the initial stellar mass function? What are the physical properties of small stellar groups, as well as stellar clusters? How do accretion discs evolve to allow grain growth and planet formation? How is angular momentum redistributed with time from molecular cloud scales down to those of individual stars? What can we learn from episodic accretion and outflow? What is the role of stellar feedback in the rapid dispersal of the parent cloud, as well as in sequential star formation? Our understanding of how stars are born to their dispersal as young moving groups, has grown enormously in the last decade. In part this is due to new facilities like ALMA and space observatories such as Herschel and GAIA, but also increasingly more powerful and realistic simulations of the processes involved.

This conference will celebrate the career of Lee Hartmann, who has made enormous contributions to our field during his productive life. For over 3 decades Lee has been a leading pioneer in characterizing the physics of molecular clouds, stars and planet formation. His scientific breadth and impact can be seen in his studies on molecular cloud formation and cloud lifetimes. This has led to a change in our paradigm of star formation towards more rapid evolution. He has been among the first to recognize the importance of accretion and magnetic fields in the phenomena observed in young stars, and has led ground-breaking efforts characterizing these effects. As a tribute to Lee, but also recognizing that we stand on the threshold of a new era with the arrival of JWST, E-ELT and SKA, it is appropriate to take stock of the most fascinating developments in our field, emphasizing those areas where Lee has made significant contributions.
