A SURVEY OF CORONAL CAVITY DENSITY PROFILES
Coronal cavities are common features of the solar corona that appear as darkened regions at the base of coronal helmet streamers in coronagraph images. Their darkened appearance indicates that theyExpand

General relativistic orbital decay in a seven-minute-orbital-period eclipsing binary system
General relativity1 predicts that short-orbital-period binaries emit considerable amounts of gravitational radiation. The upcoming Laser Interferometer Space Antenna2 (LISA) is expected to detectExpand

Most Black Holes are Born Very Slowly Rotating
The age of gravitational wave (GW) astronomy has begun, and black hole (BH) mergers detected by LIGO are providing novel constraints on massive star evolution. A major uncertainty in stellar theoryExpand

Radial velocity monitoring of Kepler heartbeat stars
Heartbeat stars (HB stars) are a class of eccentric binary stars with close periastron passages. The characteristic photometric HB signal evident in their light curves is produced by a combination ofExpand

The dynamical history of the evaporating or disrupted ice giant planet around white dwarf WD J0914+1914
Robust evidence of an ice giant planet shedding its atmosphere around the white dwarf WD J0914+1914 represents a milestone in exoplanetary science, allowing us to finally supplement our knowledge ofExpand

Orbital Decay in a 20 Minute Orbital Period Detached Binary with a Hydrogen Poor Low Mass White Dwarf
We report the discovery of a detached double white dwarf binary with an orbital period of $\approx20.6\,\rm minutes$, PTF J053332.05+020911.6. The visible object in this binary, PTF J0533+0209B, is aExpand

The first ultracompact Roche lobe-filling hot subdwarf binary.
We report the discovery of the first short period binary in which a hot subdwarf star (sdOB) fills its Roche lobe and started mass transfer to its companion. The object was discovered as part of aExpand

Elicitation of potent neutralizing antibody responses by designed protein nanoparticle vaccines for SARS-CoV-2
A safe, effective, and scalable vaccine is urgently needed to halt the ongoing SARS-CoV-2 pandemic. Here, we describe the structure-based design of self-assembling protein nanoparticle immunogensExpand

Very regular high-frequency pulsation modes in young intermediate-mass stars
Asteroseismology probes the internal structures of stars by using their natural pulsation frequencies 1 . It relies on identifying sequences of pulsation modes that can be compared with theoreticalExpand
