    Exploring the Climate of Exoplanets with OASIS

     

    In the last two decades, the astrophysical community discovered a multitude of planets orbiting other stars. The variety of planetary environments that these exoplanets may harbour is still unknown. Most importantly, this discovery propels the fundamental scientific and philosophical quest of searching for the first detection of life beyond our own planet. As more observational data become available, models of exoplanetary atmospheres are essential, at a first level to interpret the data and more importantly to reproduce...

    "Evidence of differential rotation inside Saturn from waves of its rings"


    The rotation rate of Saturn is not well constrained. This rate has been
    estimated based on several investigations of its shape (Anderson and
    Schubert 2007, Read et al., 2009 and Helled et al., 2015), its cloud top
    winds (Garcia Melendo et al., 2011, Sanchez-Lavega et al., 2014) and its
    magnetic field (Ye et al., 2010, Lamy et al., 2011, Andrews et al.,
    2012, Provan et al., 2013).  The reason why the interior rotation rate
    is not well known is that its magnetic field seems to be closely... Read more about ITC Seminar - Maryame El Moutamid (Cornell)

    Probing the Bulk Composition of Exoplanets with Engulfment Events
    As a star evolves away from the main sequence and expands in size, close-orbiting substellar companions are engulfed in the process. While such events are not uncommon, the short tidal inspiral timescale makes it challenging to directly observe a planetary engulfment event. However, traces of engulfment can be observed long after the event has transpired. In my most recent work, I explore the strength and survival time of the 7Li enrichment signature in...

    Zooming in on the early stages of star and disk formation 

     

    Abstract: Magnetized, cold, dense molecular cloud cores provide the birth environment for stars and disks. This work is aimed at understanding the multi-scale scenario of star formation, which occurs via the formation of two quasi-hydrostatic Larson cores. We perform spherically symmetric, isolated, molecular cloud collapse simulations using the radiation (magneto)hydrodynamic code PLUTO as a tool. These one-dimensional studies, spanning 7 orders of magnitude in spatial scales, include self-...

    Cosmology with Gravitational-Wave Standard Sirens

    Abstract:  Merging compact objects are useful cosmological probes because their distance is directly encoded in their gravitational waveform. Combining this distance with an independent redshift measurement, one can measure the expansion history of the universe. In this talk, I will discuss different ways of combining the gravitational-wave distance measurement with a redshift: using an electromagnetic counterpart, a catalog of galaxies, or by measuring the redshifted mass distribution. I will summarize what these...
