Global 3D Hydrodynamic Modeling of In-transit Lyα Absorption of GJ 436b

<jats:title>Abstract</jats:title> <jats:p>Using a global 3D, fully self-consistent, multifluid hydrodynamic model, we simulate the escaping upper atmosphere of the warm Neptune GJ 436b, driven by the stellar X-ray and ultraviolet (XUV) radiation impact and gravitational forces and interacting with the stellar wind. Under the typical parameters of XUV flux and stellar wind plasma expected for GJ 436, we calculate in-transit absorption in Ly<jats:italic>α</jats:italic> and find that it is produced mostly by energetic neutral atoms outside of the planetary Roche lobe, due to the resonant thermal line broadening. At the same time, the influence of radiation pressure has been shown to be insignificant. The modeled absorption is in good agreement with the observations and reveals such features as strong asymmetry between blue and red wings of the absorbed Ly<jats:italic>α</jats:italic> line profile, deep transit depth in the high-velocity blue part of the line reaching more than 70%, and the timing of early ingress. On the other hand, the model produces significantly deeper and longer egress than in observations, indicating that there might be other processes and factors, still not accounted for, that affect the interaction between the planetary escaping material and the stellar wind. At the same time, it is possible that the observational data, collected in different measurement campaigns, are affected by strong variations of the stellar wind parameters between the visits, and therefore they cannot be reproduced altogether with the single set of model parameters.</jats:p>

The Cosmic Distance Duality Relation with Strong Lensing and Gravitational Waves: An Opacity-free Test
Kai Liao
<jats:title>Abstract</jats:title> <jats:p>The cosmic distance duality relation (CDDR) is a fundamental rule in cosmological studies. Given the redshift <jats:italic>z</jats:italic>, it relates luminosity distance <jats:italic>D</jats:italic> <jats:sup> <jats:italic>L</jats:italic> </jats:sup> with angular diameter distance <jats:italic>D</jats:italic> <jats:sup> <jats:italic>A</jats:italic> </jats:sup> through <jats:inline-formula> <jats:tex-math> <?CDATA ${(1+z)}^{2}{D}^{A}/{D}^{L}\equiv 1$?> </jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="apjab4819ieqn1.gif" xlink:type="simple" /> </jats:inline-formula>. Many efforts have been made to test CDDR with various observational approaches. However, to the best of our knowledge, those methods are always affected by cosmic opacity, which could violate CDDR owing to the non-conservation of photon number. Such a mechanism is more related to astroparticle physics. In this work, in order to directly study the nature of spacetime, i.e., to disentangle it from astroparticle physics, we propose a new strategy to test CDDR, with strong lensing providing <jats:italic>D</jats:italic> <jats:sup> <jats:italic>A</jats:italic> </jats:sup> and gravitational waves (GWs) providing <jats:italic>D</jats:italic> <jats:sup> <jats:italic>L</jats:italic> </jats:sup>. It is known that the propagation of GWs is unaffected by cosmic opacity. We demonstrate that distances from observations of optical lensing are also opacity-free. These two kinds of distance measurements make it possible to test spacetime. Our results show that the constraints on the deviations of CDDR will be very competitive with current techniques.</jats:p>
