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 […]

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 […]

Stabilizing the inverted phase of a WSe$_2$/BLG/WSe$_2$ heterostructure via hydrostatic pressure

Kavli Affiliate: Srijit Goswami | First 5 Authors: Máté Kedves, Bálint Szentpéteri, Albin Márffy, Endre Tóvári, Nikos Papadopoulos | Summary: Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin–orbit interaction (SOI) induced by the proximity of transition metal dichalcogenides with large intrinsic SOI. Here, we […]

EMPRESS. XII. Statistics on the Dynamics and Gas Mass Fraction of Extremely-Metal Poor Galaxies

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Yi Xu, Masami Ouchi, Yuki Isobe, Kimihiko Nakajima, Shinobu Ozaki | Summary: We present demography of the dynamics and gas-mass fraction of 33 extremely metal-poor galaxies (EMPGs) with metallicities of $0.015-0.195~Z_odot$ and low stellar masses of $10^4-10^8~M_odot$ in the local universe. We conduct deep optical integral-field spectroscopy […]

The first X-ray polarimetric observation of the black hole binary LMC X-1

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Jakub Podgorny, Lorenzo Marra, Fabio Muleri, Nicole Rodriguez Cavero, Ajay Ratheesh | Summary: We report on an X-ray polarimetric observation of the high-mass X-ray binary LMC X-1 in the high/soft state, obtained by the Imaging X-ray Polarimetry Explorer (IXPE) in October 2022. The measured polarization is […]
