Abstract: Compact stars, such as neutron stars
or white dwarfs, often collide with bigger, non-degenerate stars.
In this interaction, the NS captures copious amounts of matter that
flows inwards. The density of the gas in this scenario is so
high...
Early results of JWST observation have revealed an unexpected
abundance of red compact objects dubbed little red dots (LRDs) at
z>4. These objects display a faint blue rest-frame UV continuum
followed by a steep red rise in the rest-frame optical...
Stars orbiting sufficiently close to massive black holes
inevitably inspiral towards the black hole due to gravitational
wave radiation. The fate of such stars is subtle and depends on an
interplay between tidal heating of the star, mass transfer...
In the last few decades, statistical analysis of cosmic
microwave background (CMB) temperature fluctuations has established
the standard model of cosmology with high precision. The next
frontier lies in measuring the spectral shape of the CMB and...
Abstract: Reconnection is regularly observed at current sheets
in the solar wind at 1AU, and the scalings of these current sheets
suggest that they are dynamically formed by the turbulence itself.
Theoretical considerations suggest that reconnection...
