Welcome, these are my latest news:
Line-transition Compression Code:
2017) identifies the strong lines that dominate the spectrum from
the large-majority of weaker lines. Repack preserves the full
line-by-line (LBL) information of the strong lines, and compresses the
opacity from the weak lines into a continuum opacity as function of
wavenumber and temperature.
Repack reproduces ~99% of the original opacity (but reducing LBL info
from ~billion to ~million lines), it considers the temperature
dependence of the lines, and works with the HITEMP, Exomol, and
Kurucz's TiO databases. The code is available at
Fitting and MCMC Code Released:
The Multi-core Markov-chain Monte Carlo (MC3, Cubillos et al.,
2017) code is a
general-purpose Python/C software to fit parameterized models to a
data set in a statistically robust manner. MC3 provides best-fit and
credible-region estimation through Levenberg-Marquardt optimization
and Differential-evolution MCMC, respectively.
The code is available at http://pcubillos.github.io/MCcubed/
Mass-loss constraints for low-density Neptune-like
Some found exoplanets have bulk densities so low that their
atmospheres cannot retain their light particles (H/He) due to Jeans
Escape, yet, only a significant H/He content can explain their low
densities. Are we not measuring well their masses? Are we
misinterpreting their radii? There is something we are not getting
(Cubillos et al., 2017).
The Python Radiative-Transfer in a Bayesian framework (Pyrat Bay), an
open-source code to model exoplanet atmospheric spectra.
Currently, I'm a post-doctoral researcher at the Space Research Institute in Graz,
Austria. There, I work with the Group for Exoplanet Characterization
and Observation (GECO) since
October 2015. My research interests are the study of extrasolar
planet atmospehres, either through transit time-series data analysis
or atmospheric modeling and retrieval.
Other interests: Tea enthusiast, astronomic
socialism, and getting better at being human.
