These atoms include both precious metals (e.g. gold) as well as radioactive elements required for geophysical processes on the Earth (e.g. thorium) and even some which are necessary on Earth for advanced life (e.g. iodine). Recent observations with both light and gravitational waves have demonstrated that at least some of these elements are formed through the merger of two neutron stars, but such a population struggles to reproduce the enrichment patterns seen in stars within the Milky Way as well apparent early enrichment in some dwarf galaxies. Instead, recent work implies that the accretion disks formed in the stellar collapse that powers a long duration gamma-ray burst could in-fact be a dominant site. If this is true we should be able to observe r-process synthesis in the associated supernovae. The presence of lanthanides in r-process material creates strong opacity, such that the signature of their 16042( 5) - 23-Jan-2020 21:37:29 - [ 2] synthesis should be a late time infrared component visible in the supernova light. Here we propose sensitive HST observations that will search for both spectroscopic and photometric evidence of the r-process, providing the opportunity to test, for the first time, if collapsars are responsible for heavy element production. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal seeks to obtain late time observations of GRB190829A with the aim of understanding if it creates heavy r-process elements. Our observational strategy has been chosen to map to observations taken at early times in terms of filters and so uses F140W rather than F160W as stated in the phase1. With this programme we seek 3 epochs of observations. The first will be taken in Feb/March 2020. It will obtain grism spectroscopy (2 orbits) in both G102 and G141. It will also obtain deep imaging in F606W and F140W. A second epoch of observations will be taken once the source emerges from the Sun in June 2020. This will consist only of F140W and F606W imaging. A third epoch should be taken in August/September 2020 and will also consist only of F606W/F140W imaging. ------------------------------------------------------------------------------------ 16042( 5) -
