Abstract: This is an exciting time for stellar
astrophysics as high-cadence time domain surveys (Gaia, PTF, ZTF,
ATLAS, Kepler, TESS, and, in the near future, the Vera Rubin
Observatory) are revolutionizing the landscape of stellar studies
by...
During the early stages of giant planet formation, the
proto-planet continuously exchanges mass and angular momentum with
the protoplanetary disks. This exchange process is believed to
happen through an extended gaseous envelope that connects
the...
Strong non-relativistic shocks are known to accelerate particles
up to relativistic energies. However, for Diffusive Shock
Acceleration electrons must have a highly suprathermal energy,
implying a need for very efficient pre-acceleration. Most...
Abstract: Gravitational waves have uncovered a
treasure trove of nearly 90 merging black holes and neutron stars,
each with its own unique story to tell. In the first part of the
talk, our focus will center on black hole spins, seeking to
decipher...
Binaries are ubiquitous in various scales and astrophysical
systems, from planetesimals to black holes, and play a key role in
the dynamics and evolution of stellar systems. I will discuss the
formation and evolution of binaries in gaseous...
Charge-exchange (CX) collisions of the solar wind (SW)
high-ionization-state minor ions with LISM neutrals are responsible
for much of X-ray production in the outer heliosphere. In this
talk, we discuss numerical modeling of the heliospheric CX X...
Current cosmological measurements have left us with deep
questions about our Universe: What caused the expansion of the
Universe at the earliest times? How did structure form? What is
Dark Energy and does it evolve with time? New experiments
like...
Pulsar timing arrays {PTAs) and gravitational wave detectors can
serve as valuable tools in the detection of dark matter. Dark
matter substructure within the Milky Way Galaxy can induce
gravitational pulls on pulsars, leading to observable...
Despite the thousands of planets discovered orbiting stars on
the main sequence, the planetary systems of more evolved stars
remain poorly understood. Studying planetary systems around
subgiant and red giant stars can reveal how planetary
systems...
