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

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$_oplus$) […]

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

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 […]

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

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 […]

The dark matter profile of the Milky Way inferred from its circular velocity curve

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anna-Christina Eilers, Lina Necib, Anna Frebel, | Summary: In this paper, we construct the circular velocity curve of the Milky Way out to $sim 30$ kpc, providing an updated model of the dark matter density profile. We derive precise parallaxes for 120,309 stars with a […]
