Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sam Christian, Andrew Vanderburg, Juliette Becker, Adam L. Kraus, Logan Pearce | Summary: Studying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 AU) can shed light on how planets form and evolve in binary systems. Previous observations by […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Johanna M. Vos, Andrew Vanderburg, Fei Dai, | Summary: We conduct a comprehensive search for transiting exomoons and exosatellites within 44 archival Spitzer light curves of 32 substellar worlds with estimated masses ranging between 3-30M$_{rm Jup}$. This sample’s median host mass is 16M$_{rm Jup}$, […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Juri Poutanen, Sergey S. Tsygankov, Victor Doroshenko, Sofia V. Forsblom, Peter Jenke | Summary: Discovery of pulsations from a number of ultra-luminous X-ray (ULX) sources proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by a couple of orders of magnitude. The […]

Forsblom, Peter Jenke | Summary: Discovery of pulsations from a number of ULXs proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by several orders of magnitude. The conditions necessary to achieve such […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Hillary Diane Andales, Ananda Santos Figueiredo, Casey Gordon Fienberg, Mohammad K. Mardini, Anna Frebel | Summary: We present a detailed chemical abundance and kinematic analysis of six extremely metal-poor ($-4.2 leq$ [Fe/H] $leq-$2.9) halo stars with very low neutron-capture abundances ([Sr/H] and [Ba/H]) based on high-resolution Magellan/MIKE […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ole König, Guglielmo Mastroserio, Thomas Dauser, Mariano Méndez, Jingyi Wang | Summary: The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies ${<}1$ keV across all states. The hard state power spectrum can be decomposed into […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Riccardo Ferrazzoli, Dmitry Prokhorov, Niccolò Bucciantini, Patrick Slane, Jacco Vink | Summary: Supernova remnants (SNRs) provide insights into cosmic-ray acceleration and magnetic field dynamics at shock fronts. Recent X-ray polarimetric measurements by the Imaging X-ray Polarimetry Explorer (IXPE) have revealed radial magnetic fields near particle acceleration […]
