Exoplanet Astronomy
Christina Hedges
Institute of Astronomy, Cambridge UK
I am a PhD student working at the Institute of Astronomy at the University of Cambridge with Simon Hodgkin. I am also associated with Murray Edwards College and am involved with the graduate students there. My research interests surround exoplanet detection and characterisation with my current projects based on exoplanet atmospheres.
I work mostly with IDL and C++ and develop tookits and pipelines for the reduction of datasets. Primarily I am working on a reduction toolkit for HST spatial scan mode data. Previously I have worked with the Kepler data and asteroseismology. I was also lucky enough to be selected for an REU position at LASP in Colorado Boulder in the summer of 2012 where I worked with Dr. Savita Mathur learning to develop pipelines for the detection and analysis of asteroseismic signatures in Kepler data.
I also have a blog which you can find here which includes updates on neat things I've found during my PhD and code snippets for people to use such as new IDL color tables.
Outreach Talks
As part of my PhD at the Institute of Astronomy I'm involved in a wide range of outreach activities, from public observing nights to tours of the telescopes on site. I have also give public talks during outreach events which the Institute holds between October and March. A few outreach materials are available here and talks slides are available below.
Course Materials
During my PhD I have developed a short introductory course to C++ for new graduate students. The materials for C++ Course are below with each of the worksheet sets and solutions in a .tar.gz file.
Workshop 1
Basic Program Structure
Workshop one covering the basics of C++ programming with three example sheets including solutions. The example sheets and solutions can be downloaded here.
Workshop 2
Building more complex programs
Second workshop covering iteration and flow control including more complex examples. The example sheets and solutions can be downloaded here.
Workshop 3
Arrays and memory
Working with arrays and the vector library and allocating memory. The example sheets and solutions can be downloaded here.
Workshop 4
Building complex functions and librarys
Tutorial on building useful functions and libraries as well as using classes. The example sheets and solutions can be downloaded here.
Talks and Publications
What you need to know about pressure broadening in exoplanet atmospheres.
Poster, Exoplanet Community Meeting 2016
My poster for the 2016 Exoplanet Community Meeting discussing three key points from my paper from January 2016. These include the importance of broadening profile shape, the broadening molecule and the resolution of the observations.
