Stability and detectability of exomoons orbiting HIP 41378 f, a temperate Jovian planet with an anomalously low apparent density

Posted by dbos March 24, 2023MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Caleb K. Harada, Courtney D. Dressing, Munazza K. Alam, James Kirk, Mercedes Lopez-Morales | Summary: Moons orbiting exoplanets ("exomoons") may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the temperate ($T_text{eq}=294$ K) giant ($R = 9.2$ R$_oplus$) […]

Leveraging vision to understand curiosity

Posted by klaurent March 23, 2023March 27, 2023Columbia

Kavli Affiliate: Jacqueline Gottlieb | Authors: Michael Cohanpour, Mariam Aly and Jacqueline Gottlieb | Summary: Humans are immensely curious and motivated to reduce uncertainty. Inspired by studies of sensory uncertainty, we hypothesized that visual areas provide multivariate representations of uncertainty, which are read out by higher-order areas that encode confidence and, ultimately, translated into curiosity. […]

Orbital decay in an accreting and eclipsing 13.7 minute orbital period binary with a luminous donor

Posted by klaurent March 23, 2023MIT

Kavli Affiliate: Saul Rappaport | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Saul Rappaport, Tin Long Sunny Wong, Evan B. Bauer | Summary: We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. The system contains a white dwarf accretor, which likely originated as a post-common […]

The Quantization Model of Neural Scaling

Posted by dbos March 23, 2023MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Eric J. Michaud, Ziming Liu, Uzay Girit, Max Tegmark, | Summary: We propose the Quantization Model of neural scaling laws, explaining both the observed power law dropoff of loss with model and data size, and also the sudden emergence of new capabilities with scale. We derive this […]

A tight universal relation between the shape eccentricity and the moment of inertia for rotating neutron stars

Posted by klaurent March 23, 2023Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Yong Gao, Lijing Shao, Jan Steinhoff, , | Summary: Universal relations that are insensitive to the equation of state (EoS) are useful in reducing the parameter space when measuring global quantities of neutron stars (NSs). In this paper, we reveal a new universal relation that connects the […]
