561“…In neutron stars the ultra-dense matter might support extremely high magnetic fields, far beyond anything that can be produced in the laboratory, significantly affecting the stellar properties. At very high densities general relativity predicts the stellar collapse to a black hole. …”

562“…Once added to the model, the cosmographic error budget should become dependent on stellar kinematics uncertainties. We propose that a core component coexisting with a cusp could bring the lensing measurements of $H_0$ into accordance with the CMB/LSS value.…”

563“…We highlight that the inspiral phases of known stellar-mass compact binaries cumulatively produce a signal well within reach of the proposed AION-km and AEDGE experiments which will need to be accounted for in the gravitational wave programs of these experiments. …”

565“…This importance is demonstrated in this volume with the description of a number of topics in astrophysics, including quantum optics, cataclysmic variables, pulsars, X-ray binaries and stellar pulsations to name a few. Underlining this science foundation, technological developments in both instrumentation and detectors are described. …”

569por Kopp, Joachim“…First, we argue that subhalos of the Milky Way's dark matter halo traveling through the disk will leave a characteristic imprint in the motion of nearby stars. These "stellar wakes" can be probed using precise astrometric data, for instance from Gaia. …”

570por Krauss, L“…For almost 70 years, since Hubble's discovery that the Universe is expanding, there has been a constant tension between the age of the Universe, as determined from the Hubble expansion, and the age as determined from stellar evolution estimates of our galaxy. I will describe the issues and the current status of this controversy, including new results stemming from the Hipparcos satellite measuring parallaxes of nearby stars which suggest that for the first time in recent memory the lower limit on the age of the universe based on globular cluster ages may be in accord with the upper limit obtained from the Hubble constant, even for a flat, matter dominated universe. …”

573por Sellwood, J A“…The global bar stability of the disc is not greatly affected by the interaction between the two stellar populations, and it is found that a large fraction of the total galactic mass is still required in the spheroidal component if bar formation is to be prevented. (36 refs).…”

S., Haydon, Daniel T., McLeod, Anna F., Dalcanton, Julianne J., Tacconi, Linda J., van Dishoeck, Ewine F.“…We apply a novel statistical method15, 16 to quantify the evolutionary timeline and find that star formation is regulated by efficient stellar feedback, driving GMC dispersal on short timescales (~1.5 Myr) due to radiation and stellar winds, prior to supernova explosions. …”

It determines the magnetospheric environment of the earth and other planets; it forms the research frontier in such areas as nuclear fusion, advanced accelerators, and high power lasers; and its applications to various industrial processes (such as computer chip manufacture) are rapidly increasing. …”
