Data on HII regions, molecular clouds, and methanol masers have been used to estimate the Sun's distance from the symmetry plane z ⊙ and the vertical disk scale height h. Kinematic distance estimates are available for all objects in these samples. The Local-arm (Orion-arm) objects are shown to affect noticeably the pattern of the z distribution. The deviations from the distribution symmetry are particularly pronounced for the sample of masers with measured trigonometric parallaxes, where the fraction of Local-arm masers is large. The situation with the sample of HII regions in the solar neighborhood is similar. We have concluded that it is better to exclude the Local arm from consideration. Based on the model of a self-gravitating isothermal disk, we have obtained the following estimates from objects located in the inner region of the Galaxy (R ≤ R 0 ) : z ⊙ = −5.7 ± 0.5 pc and h 2 = 24.1 ± 0.9 pc from the sample of 639 methanol masers, z ⊙ = −7.6±0.4 pc and h 2 = 28.6±0.5 pc from 878 HII regions, z ⊙ = −10.1±0.5 pc and h 2 = 28.2 ± 0.6 pc from 538 giant molecular clouds.

“…Nearby clusters of O-B2.5 massive stars that are progenitors of core-collapse Type II and Type Ib/c supernovae form a thin planar ring-like structure around the Sun known as "Gould's Belt" [21,22,23]. Gould's Belt is part of a large-scale warp in Fig.…”

A range of astronomical data indicates that ancient supernovae created the galactic environment of the Sun and sculpted the physical properties of the interstellar medium near the heliosphere. In this paper we review the characteristics of the local interstellar medium that have been affected by supernovae. The kinematics, magnetic field, elemental abundances, and configuration of the nearest interstellar material support the view that the Sun is at the edge of the Loop I superbubble, which has merged into the low density Local Bubble. The energy source for the higher temperature X-ray emitting plasma pervading the Local Bubble is uncertain. Winds from massive stars and nearby supernovae, perhaps from the Sco-Cen Association, may have contributed radioisotopes found in the geologic record and galactic cosmic ray population. Nested supernova shells in the Orion and Sco-Cen regions suggest spatially distinct sites of episodic star formation. The heliosphere properties vary with the pressure of the surrounding interstellar cloud. A nearby supernova would modify this pressure equilibrium and thereby severely disrupt the heliosphere as well as the local interstellar medium.

“…We applied this method to Stage 3 candidates using the PARSEC (Bressan et al 2012) stellar evolution models. Since GB members are young stars with ages between 30 and 80 Myr (Fresneau et al 1996;Guillout et al 1998), we adopted 10 Myr to be the lower limit to eliminate Classical T Tauri Stars (Bobylev 2014) and 100 Myr (Wichmann et al 2003) to be the upper limit for this study to make up for errors. The age distribution of XRAVE is shown in Fig.…”

In this paper the results of matching the RAdial Velocity Experiment (RAVE), a spectroscopic Southern hemisphere survey (9 < I DEN IS < 12), and XMM-Newton Serendipitous Source Catalogue (3XMM) are presented. The latest data releases of RAVE and XMM were matched and a X-ray RAVE catalogue of 1071 stars was obtained. Then the catalogue was checked for possible Gould Belt (GB) members. We obtained a subsample of 10 stars that meet the GB membership criteria. This subsample and GB member candidates were tested photometrically and kinematically. Among the members there are two BY Dra type variables, an NGC2451 open cluster member, a high proper motion star. The rest are regular main sequence stars. The members have very low velocity dispersions which lead us to think that the members belong in a single structure. We also found out that a kinematical GB membership test might be possible to derive given a large enough GB member sample as they fit in a narrow interval in space velocity diagrams.
