Gravity modes and potential evidence for Rossby Waves in late O-type supergiants
Lydia S. Cidale, Alejandra Christen, Aldana Alberici Adam +6
The properties of O-type supergiant stars remain largely unexplored. By analysing their light variations, we can unravel underlying physical phenomena, such as binarity, stellar pu…
Analytical Solutions for Radiation-Driven Winds in Massive Stars II: The -slow Regime
I. Araya, A. Christen, M. Curé +7
Accurate mass-loss rates and terminal velocities from massive stars winds are essential to obtain synthetic spectra from radiative transfer calculations and to determine the evolut…
AutoRegressive Planet Search: Application to the Kepler Mission
Gabriel A. Caceres, Eric D. Feigelson, G. Jogesh Babu +5
The 4-year light curves of 156,717 stars observed with NASA's Kepler mission are analyzed using the AutoRegressive Planet Search (ARPS) methodology described by Caceres et al. (201…
A method to deconvolve stellar rotational velocities III. The probability distribution function via Maximum Likelihood utilizing Finite Distribution Mixtures
Rafael Orellana, Pedro Escarate, Michel Cure +3
The study of accurate methods to estimate the distribution of stellar rotational velocities is important for understanding many aspects of stellar evolution. From such observations…
AutoRegressive Planet Search: Methodology
Gabriel A. Caceres, Eric D. Feigelson, G. Jogesh Babu +5
The detection of periodic signals from transiting exoplanets is often impeded by extraneous aperiodic photometric variability, either intrinsic to the star or arising from the meas…
A method to deconvolve stellar rotational velocities II
A. Christen, P. Escarate, M. Cure +2
Knowing the distribution of stellar rotational velocities is essential for the understanding stellar evolution. Because we measure the projected rotational speed vsini, we need to…
Quantitative exponential bounds for the renewal theorem with spread-out distributions
J. -B Bardet, A Christen, J Fontbona
We establish explicit exponential convergence estimates for the renewal theorem, in terms of a uniform component of the inter arrival distribution, of its Laplace transform which i…
A method to deconvolve mass ratio distribution from binary stars
Michel Cure, Diego F. Rial, Alejandra Christen +2
To better understand the evolution of stars in binary systems as well as to constrain the formation of binary stars, it is important to know the binary mass-ratio distribution. How…
A method to deconvolve stellar rotational velocities
Michel Cure, Diego F. Rial, Alejandra Christen +1
Rotational speed is an important physical parameter of stars and knowing the distribution of stellar rotational velocities is essential for the understanding stellar evolution. How…
Total variation estimates for the TCP process
Jean-Baptiste Bardet, Alejandra Christen, Arnaud Guillin +2
The TCP window size process appears in the modeling of the famous Transmission Control Protocol used for data transmission over the Internet. This continuous time Markov process ta…
