Planet formation mechanisms

Planet formation encompasses processes that span a remarkable 40 magnitudes in mass, ranging from collisions between micron-sized grains inherited from the ISM to the accretion of gas by giant planets. The planet formation process takes place in the interior of dusty disks, which offer us only limited observational constraints.

Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels

Advanced Optical Materials, EarlyView.
Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Early Planet Formation in Embedded Disks (eDisk). XIV. Flared Dust Distribution and Viscous Accretion Heating of the Disk around R CrA IRS 7B-a

The Astrophysical Journal
We performed radiative transfer calculations and observing simulations to reproduce the 1.3 mm dust-continuum and C ^18 O (2–1) images in the Class I protostar R CrA IRS7B-a, observed with the ALMA Large Program “Early Planet Formation in Embedded Disks (

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

Advanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Planetesimal Drift in Eccentric Disks: Possible Outward Migration

The Astrophysical Journal
Radial drift of solid particles in the protoplanetary disk is often invoked as a threat to planet formation, as it removes solid material from the disk before it can be assembled into planets.
