Stellar Distances by the Baade-Wesselink Method [PDF]

open access: yesSymposium - International Astronomical Union, 1997
Galactic and extragalactic distances to Cepheid variable stars according to a modern realization of the geometric Baade-Wesselink method are presented. Reliable results as accurate as few percent are currently achievable, allowing the cosmic distance scale calibration to be significantly improved with respect to previous calibrations.

Semiresolved Stellar Populations as Distance Indicators

open access: yesThe Astrophysical Journal Letters
Galaxy distances are central to our understanding of the Universe. Despite the success of existing approaches, independent and complementary methods remain valuable for testing systematic effects and extending the applicability range of different ...

Dynamics of stellar and HI streams in the Milky Way halo

open access: yesEPJ Web of Conferences, 2012
Stellar streams are key players in many aspects of Milky Way studies and, in particular, studying their orbital dynamics is crucial for furthering our understanding of the Milky Wayʼs gravitational potential.

A New Wide-field Infrared Survey Explorer Calibration of Stellar Mass

open access: yesThe Astrophysical Journal, 2023
We derive new empirical scaling relations between Wide-field Infrared Survey Explorer (WISE) mid-IR (MIR) galaxy photometry and well-determined stellar masses from spectral energy distribution modeling of a suite of optical–infrared photometry provided ...

Stellar Distance and Velocity (II)

open access: yesInternational Journal of Science and Research (IJSR), 2019
The use of parallax angles is one of the standard methods for determining stellar distance. The problem that arises in using this method is how to measure that angle. In order for the measurement to be correct, it is necessary for the object we are observing to be stationary in relation to the sun. This is generally not true.

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

open access: yesPediatric 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 ...

Disk accretion onto a magnetized star

open access: yesEPJ Web of Conferences, 2014
The problem of interaction of the rotating magnetic field, frozen to a star, with a thin well conducting accretion disk is solved exactly. It is shown that a disk pushes the magnetic field lines towards a star, compressing the stellar dipole magnetic ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

SpecDis: Value Added Distance Catalog for 4 Million Stars from DESI Year-1 Data

open access: yesThe Astronomical Journal
We present the S pec D is value-added stellar distance catalog accompanying DESI Data Release 1. S pec D is trains a feed-forward neural network (NN) with Gaia parallaxes and gets the distance estimates. To build up an unbiased training sample, we do not
