The Birth of Be Star Disks. II. A High-resolution Spectroscopic Campaign and TESS Observations of an Outburst of the Classical Be Star λ Pavonis

open access: yesThe Astrophysical Journal
Be stars are rapidly rotating B stars that have shown emission lines originating in a circumstellar disk. The mechanisms that lead to disk formation and dissipation are not known although progress has been made with some systems.

P-STARS

open access: yesInternational Journal of Modern Physics D, 2004
P-Stars are a new class of compact stars made of up and down quarks in β-equilibrium with electrons in an Abelian chromomagnetic condensate. We show that P-Stars are able to account for compact stars with R≲6 Km , as well as stars with radius comparable with canonical Neutron Stars.

Bone Mineral Density After Contemporary Treatment for Acute Lymphoblastic Leukaemia: A Matched Cross‐Sectional Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Reduced bone mineral density (BMD) has been reported in survivors of childhood and young adult acute lymphoblastic leukaemia (ALL); however, data from cohorts treated with contemporary protocols and including matched controls remain limited.

Using the Coolest Ae Stars to Constrain Circumstellar Disk Viscosity

open access: yesThe Astrophysical Journal
Classical Ae (CAe) stars are main-sequence, A-type stars with H α emission but no signature of dust. They are thought to be the cool extension of the classical Be stars to lower masses.

Equilibria and oscillations of magnetised neutron stars

open access: yes, 2010
We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

A Be Star + He Star Binary as an Indicator of a Binary Mass Transfer Phase

open access: yesThe Astrophysical Journal
The rapid rotation of Be stars is supposed to mainly originate from binary evolution. In recent years, more and more Be stars with helium (He) star companions have been discovered, which provides a significant opportunity to study binary interaction ...

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

X-ray Transient Sources (Multifrequency Laboratories) The Case of the Prototype A0535+26/HDE 245770

open access: yesActa Polytechnica, 2011
The goal of this paper is to discuss the behaviour of the X-ray transient source A0535+26 which is considered for historical reasons and for the huge amount of multifrequency data, spread over a period of 35 years, as the prototype of this class of ...
