Massive runaway stars in the Large Magellanic Cloud [PDF]

, 2010
The origin of massive field stars in the Large Magellanic Cloud (LMC) has long been an enigma. The recent measurements of large offsets (~100 km/s) between the heliocentric radial velocities of some very massive (O2-type) field stars and the systemic LMC

Using numerical models of bow shocks to investigate the circumstellar medium of massive stars

, 2014
Many massive stars travel through the interstellar medium at supersonic speeds. As a result they form bow shocks at the interface between the stellar wind.

Ks- andLp-band polarimetry on stellar and bow-shock sources in the Galactic center [PDF]

Astronomy & Astrophysics, 2013
Infrared observations of the Galactic center (GC) provide a unique opportunity to study stellar and bow-shock polarization effects in a dusty environment. The goals of this work are to present new Ks- and Lp-band polarimetry on an unprecedented number of sources in the central parsec of the GC, thereby expanding our previous results in the H- and Ks ...

Searching for Faint X-Ray Emission from Galactic Stellar Wind Bow Shocks

The Astronomical Journal, 2019
Abstract We present a stacking analysis of 2.61 Ms of archival Chandra observations of stellar wind bow shocks. We place an upper limit on the X-ray luminosity of infrared-detected bow shocks of <2 × 1029 erg s−1, a more stringent constraint than has been found in previous archival studies and dedicated observing campaigns of nearby ...

The Interaction of Asymptotic Giant Branch Stars with the Interstellar Medium [PDF]

, 2012
We study the hydrodynamical behavior of the gas expelled by moving Asymptotic Giant Branch Stars interacting with the ISM. Our models follow the wind modulations prescribed by stellar evolution calculations, and we cover a range of expected relative ...

On the observability of bow shocks of Galactic runaway OB stars

, 2016
Massive stars that have been ejected from their parent cluster and supersonically sailing away through the interstellar medium (ISM) are classified as exiled. They generate circumstellar bow shock nebulae that can be observed. We present two-dimensional,

H₂O masers in a jet-driven bow shock: episodic ejection from a massive young stellar object [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We report the results of VERA multi-epoch VLBI 22 GHz water maser observations of S255IR-SMA1, a massive young stellar object located in the S255 star forming region. By annual parallax the source distance was measured as D = 1.78 +-0.12 kpc and the source systemic motion was (u alpha cos d, u d) = (-0.13 +- 0.20, -0.06 +- 0.27) mas yr-1. Masers appear

Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...
