Entropy and diffusion characterize mutation accumulation and biological information loss
Stephan Baehr, Hans Baehr
Aging is a universal consequence of life, yet researchers have identified no universal theme. This manuscript considers aging from the perspective of entropy, wherein things fall a…
Dust Morphology Under Changing Dust Mass Ratios in Protoplanetary Discs
Matthew Murray, Cassandra Hall, Hans Baehr +1
Protoplanetary disc mass is one of the most fundamental properties of a planet-forming system, as it sets the total mass budget available for planet formation. However, obtaining d…
On the Gravitational Collapse of Small Dust Grains in Self-gravitating Disk Structures
Hans Baehr, Ken Rice, Chao-Chin Yang +1
Planet formation may begin much earlier than previously expected, when the protoplanetary disk is still massive and gravitationally unstable. It has been proposed that solid grains…
Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs
Ken Rice, Hans Baehr, Alison K Young +5
Planet formation via core accretion involves the growth of solids that can accumulate to form planetary cores. There are a number of barriers to the collisional growth of solids in…
Turbulence Inhibits Planetesimal Formation in Class 0/I Disks Subject to Infall
Daniel Carrera, Abigail Davenport, Jacob B. Simon +5
There is growing evidence that planet formation begins early, within the Myr Class 0/I phase, when infall dominates disk dynamics. Our goal is to determine if Class 0/I…
