An Ultraviolet View of Stellar Winds [PDF]
Symposium - International Astronomical Union, 1979 Ultraviolet observations of mass-loss effects in O stars have, over the past decade, revealed a broad picture of a phenomenon whose extent was only partially evident from earlier ground-based observations. Ultraviolet resonance lines of a variety of ionization stages of several common elements provide a comprehensive probe of the low-density, extended ...

Relativistic stellar jets: dynamics and non-thermal radiation
EPJ Web of Conferences, 2013 Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.

Observational evidences of stellar wind [PDF]
International Astronomical Union Colloquium, 1981 AbstractObservations mainly from the IUE Spectra of HD 152236 (Blla) have been used to provide support to the various aspects of the theory of stellar wind (SW) and its interaction with the interstellar medium (ISM). Lines arising from excited levels connected radiatively to the ground level tend to be more frequent and/or strong compared to those ...

Line-driven Radiative Winds in B-supergiants: Bridging the Gap between Fast and Slow m-CAK Solutions
The Astrophysical JournalThe modified Castor, Abbott, and Klein (m-CAK) theory predicts different wind regimes based on the line force parameter for changes in ionization ( δ ) and the rotation parameter (Ω).

Pediatric Blood &Cancer, EarlyView.ABSTRACT Results of COG ANBL1221 changed treatment paradigms for patients with relapsed/refractory neuroblastoma. Chemoimmunotherapy with irinotecan/temozolomide/dinutuximab is now used as both bridge therapy following suboptimal response to induction and as treatment in first relapse.

Interaction between Winds from Weak-lined T Tauri Stars with Exoplanetary Magnetospheres
The Astrophysical JournalT Tauri stars, in more advanced stages of evolution, during the final accretion phase of stellar formation, exhibit intense stellar winds and surface magnetic fields with intensities around a kilogauss.

Radiatively-driven stellar winds [PDF]
International Astronomical Union Colloquium, 1986 In this review, attention will be focussed exclusively on the winds of hot stars, concentrating for the most part on spectral types 0 and B. For these stars, a clear consensus has emerged that it is the gradient of selective radiation pressure - i.e., line-driving - that explains the high terminal velocities, typically ~ 2000 km s−1, of their winds ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...

Symposium - International Astronomical Union, 1979 The region of the O VI resonance doublet around 1030 Å has been observed in 9 stars with the high resolution (0.051 Å FWHM) detector on the Copernicus satellite spectrometer. Although the spectra are confused with interstellar Lyman β and H2 absorption, P Cygni profiles or shifted absorption lines indicating mass flow were found in ζ Pup (O4If), 15 Mon

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An earlier study on children diagnosed with acute lymphoblastic leukemia (ALL) at Moi Teaching and Referral Hospital (MTRH) in Kenya reported a low event‐free survival (EFS), excess treatment abandonment, and high induction mortality.
