Prebiotic magnetite enables chirality-magnetic surface feedback
Jose A. P. M. Devienne, Ziwei Liu, Clancy Z. Jiang +5
The emergence of biomolecular homochirality requires both an initial symmetry-breaking event and a mechanism to amplify and preserve a chiral imbalance. Magnetic minerals have been…
Identifying Exoplanets with Deep Learning VI. Enhancing neural network mitigation of stellar activity RV signals with additional metrics
Naomi McWilliam, Zoë L. de Beurs, Andrew Vanderburg +12
The measurement of exoplanet masses using the radial velocity (RV) technique is currently limited by stellar activity, which introduces quasiperiodic variability signals that must…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Temperature-Enhanced Coercive Field by Chiral Molecules
Yael Kapon, Lilach Brann, Shira Yochelis +4
The chiral-induced spin selectivity (CISS) effect demonstrates a strong coupling between electron spin and molecular chirality, enabling spin-controlled interactions between chiral…
Applied Astrobiology: An Integrated Approach to the Future of Life in Space
Robin Wordsworth, Collin Cherubim, Shannon Nangle +13
Searching for extraterrestrial life and supporting human life in space are traditionally regarded as separate challenges. However, there are significant benefits to an approach tha…
Chiral Phonons Enhance Ferromagnetism
Jonas Fransson, Yael Kapon, Lilach Brann +4
Recent experiments suggest that the conditions for ferromagnetic order in, e.g., magnetite, can be modified by adsorption of chiral molecules. Especially, the coercivity of magneti…
