We have many viewing geometries of Ivar where we were able to collect both visible and thermal data.  



Current best shape model of 2003 YT1 primary with 2004 observations from Arecibo Observatory: 


On the left, is the model of YT1 as seen by the observer and on the right, we show the radar image resulting from the model on the left.  As with most radar images, the y-axis represents distance from the observer and the x-axis represents radial velocity (with the center representing 0).

It looks like I will soon be wrapping up the thermophysical modeling of Ivar &

I am also starting the shape modeling of 2003 YT1




 My paper has been accepted for publication in Icarus!

My poster won the 2017 Asia Oceania Geosciences Society's (AOGS) Best Student Poster Competition for Planetary Sciences!  There were many wonderful posters there.  Check out those that won in other sections here.

 Thank you SSERVI  for making it possible for me to go!


It is still awesome how much we can do with ground based observations.  Using radar and lightcurve data, we can get a pretty good idea of the shape of an asteroid.  With near-IR, we can then map out homogeneity on the surface.  With ground based observations, we can map out an asteroid that we have never gone to before and describe it is such astonishing detail.
