TL;DR: In this paper, the authors compare the He and combined O + Ne flow distributions for two interstellar flow passages in 2009 and 2010 with an analytical calculation, which is simplified because the IBEX orientation provides observations at almost exactly the perihelion of the gas trajectories.

TL;DR: In this paper, a comparison between recent IBEX NISHe observations and simulations carried out using a well-tested quantitative simulation code is presented, indicating a previously undetected secondary population of neutral helium produced by interaction of interstellar helium with plasma in the outer heliosheath.

TL;DR: In this paper, the authors compare the results from two major analysis approaches led by IBEX groups in New Hampshire and Warsaw and adjust the question of the distance upstream to the pristine interstellar medium and adjust both sets of results to a common distance of ~1000 AU.

TL;DR: The model they have developed suggests that the interstellar magnetic field plays a stronger role than previously thought, and detection of H, He, and O flowing into the heliosphere from the interstellar medium tells us about the authors' local interstellar environment.

TL;DR: In this paper, the authors examined data from 2012-2014 and compare results from an analytic analysis and a detailed computer model, showing that the heliosphere's interstellar interaction is likely far more complex and interesting than previously appreciated.
