Nov 30, 2018
We analysed 30 RR Lyrae stars (RRLs) located in the Large Magellanic Cloud (LMC) globular cluster Reticulum that were observed in the 3.6 and 4.5 $\mu$m passbands with the Infrared Array Camera (IRAC) on board of the Spitzer...

Protoplanetary Disks as (Possibly) Viscous Disks
RR Rafikov
Sep 02, 2019
Protoplanetary disks are believed to evolve on Myr timescales in a diffusive
(viscous) manner as a result of angular momentum transport driven by internal
stresses. Here we use a sample of 26 protoplanetary disks resolved by...

Brazilian Mangroves
Mangroves are known for large carbon stocks and high sequestration rates in biomass and soils, making these intertidal wetlands a cost-effective strategy for some nations to compensate for a portion of their carbon...

We present new theoretical period-luminosity-metallicity (PLZ) relations for RR Lyræ stars (RRLs) at Spitzer and WISE wavelengths. The PLZ relations were derived using nonlinear, time-dependent convective hydrodynamical...
Secular dynamics of binaries in stellar clusters - II. Dynamical evolution
Dense stellar clusters are natural sites for the origin and evolution of
exotic objects such as relativistic binaries (potential gravitational wave
sources), blue stragglers, etc. We investigate the secular dynamics of a...
