Maser traced accretion bursts have deepened the field of observation investigations into the high-mass star formation process. To date, 3 high-mass protostellar accretion events have been documented, while several more are now being identified in archival data sets. However, the question of whether accretion bursts cause long-lasting influence on the protostellar environment (which would in turn influence its subsequent evolution) has not been observationally investigated. Two high-mass protostars, S255IR-NIRS3 and G188.95-0.89 are maser-traced accretion burst targets which are now in the post-burst phase (the latter identified in archival monitoring data). In this experiment we propose to return to re-image the maser emission in these sources and compare the pre- and post-burst maser landscapes to investigate the aftermath of high-mass protostellar accretion bursts.
