New Nature paper on the origins of the peculiar Kuiper-belt object Ultima Thule

April 21, 2020

Our new Nature paper lead by Evgeni Grishin explains the origin of the peculiar Kuiper-belt object Ultima-Thule from quasi-secular evolution.

Winning the ERC consolidator grant SNeX (2M Euro)

January 31, 2020

Starting August 2020 we begin the SNeX ERC consolidator grant st 2020 exploring the origin of thermonuclear supernovae. The grant will allow us to explore novel ideas for the origins of type Ia supernovae and other transients, using cutting edge tools and hardware. Student and postdocs are welcome to join this exciting research.

Faint rapid red transients from Neutron star -- CO white-dwarf mergers

September 02, 2019

A new paper by PhD student Yossef Xeanti about a novel type of faint red rapid transients from the mergers of neutron stars with white dwarfs.

Planet seeding: a new paradign for the early stages of planet formation

September 30, 2018

In a new paper we propose that interstellar planetesimals can be captured by the gaseous protoplanetary disk of newly formed systems, and provide a seed for planetary growth. Thereby potentially solving the main challenges arising from  the "meter-size barrier problem"  in planet formation models.

A novel model for the origin of binary-mergers graviational wave sources

February 26, 2019

In a new paper we show that ultra-wide binaries perturbed by flyby encounters with field stars can become highly eccentric and give rise to gravitational-wave sources with unique properties produced at high rates.

The importance of being wide: A new paper about wide triples and common envelope evolution

February 03, 2019

In this new paper we propose a novel method of using wide triples to constrain common-envelope evolution, and suggest that the time-scale for common-envelope ejection is far longer than previously thought, suggesting long-lived processes rather than dynamical processes give rise to common-envelope ejection. 


Rapidly evolving supernovae from mergers of neutron stars with white dwarfs

January 26, 2020

In our new paper we made new hydrodynamical models of mergers between neutron stars and white dwarfs showing them to produce faint, likely rapidly evolving supernovae, possibly explaining the origin of supernovae such as SN 2010X and SN 2005ek.
