Tides and angular momentum redistribution inside low-mass stars hosting planets: a first dynamical model [PDF]

, 2016
We introduce a general mathematical framework to model the internal transport of angular momentum in a star hosting a close-in planetary/stellar companion. By assuming that the tidal and rotational distortions are small and that the deposit/extraction of

Direct evidence of a sub-stellar companion around CT Cha

, 2008
In our ongoing search for close and faint companions around T Tauri stars, we found a very faint (Ks=14.9mag, Ks_0=14.4mag) object, just ~2.67" northwest of the Chamaeleon star-forming region member CT Cha corresponding to a projected separation of ...

Three-dimensional simulations of the interaction between Type Ia supernova ejecta and their main sequence companions

, 2012
The identity of the progenitor systems of SNe Ia is still uncertain. In the single-degenerate (SD) scenario, the interaction between the SN blast wave and the outer layers of a main sequence (MS) companion star strips off H-rich material which is then ...

Detecting the Companions and Ellipsoidal Variations of RS CVn Primaries: I. sigma Geminorum [PDF]

, 2015
To measure the properties of both components of the RS CVn binary sigma Geminorum (sigma Gem), we directly detect the faint companion, measure the orbit, obtain model-independent masses and evolutionary histories, detect ellipsoidal variations of the ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

WIMP dark matter hidden behind its companion

Physics Letters B, 2022
The WIMP dark matter (DM) hypothesis now is in an awkward position, owing to the present strong exclusion from DM direct detection. In this article we design a mechanism to evade this constraint. The idea is simple.

The Directly Imaged Planet around the Young Solar Analog 1RXS J160929.1-210524: Confirmation of Common Proper Motion, Temperature and Mass

, 2010
Giant planets are usually thought to form within a few tens of AU of their host stars, and hence it came as a surprise when we found what appeared to be a planetary mass (~0.008 Msun) companion around the 5 Myr-old solar mass star 1RXS J160929.1-210524 ...

Companion eccentricity diffusion & multiple populations: the companion accretion model

, 2023
Globular clusters exhibit abundance variations, defining ‘multiple populations’, which have prompted a protracted search for their origin since the 1970s. In this talk, I discuss a novel model to explain these variations, the 'companion accretion model'. An overlooked characterstic of the dynamical perturbation cross-section for binaries in hot stellar

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Improved radial velocity orbit of the young binary brown dwarf candidate ChaHa8

, 2010
The very young brown dwarf candidate ChaHa8 was recently discovered to have a close (~1AU) companion by means of radial velocity monitoring. We present additional radial velocity data obtained with UVES/VLT between 2007 and 2010, which significantly ...
