A stellar wind module has been developed for the PHOENIX stellar atmosphere code for the purpose of computing non-LTE, line-blanketed, expanding atmospheric structures and detailed synthetic spectra of hot luminous stars with winds. We apply the code to observations of Deneb, for which we report the first positive detections of millimeter and centimeter emission (obtained using the Submillimeter Common-User Bolometric Array and the Very Large Array) as well a strong upper limit on the 870 μm… 

Testing spherical, expanding, line-blanketed model atmospheres of giant stars with interferometry

We show examples of PHOENIX stellar atmosphere model simulations for data obtained by long-baseline optical interferometers. A single spherical, hydrostatic model atmosphere for the M-type giant star

Quantitative spectroscopy of ba-type supergiants

Luminous BA-type supergiants have enormous potential for modern astrophysics. They allow topics ranging from non-LTE physics and the evolution of massive stars to the chemical evolution of galaxies

High Resolution UV Spectroscopy for the study of A-type Supergiants atmospheres

A-type supergiants are intrinsically the brightest stars at visual wavelengths, and therefore one of the best potential extragalactic distance indicators. These stars present a complex atmospheric

VLT/UVES spectroscopy of Wray 977, the hypergiant companion to the X-ray pulsar GX301-2

Model atmosphere fits to high-resolution optical spectra of Wray 977 confirm the B hypergiant classification of the massive companion to the X-ray pulsar GX301−2. The models give a radius of 62 R� ,a

Quantitative Spectroscopy of Deneb

Context. Quantitative spectroscopy of luminous BA-type supergiants offers a high potential for modern astrophysics. Detailed studies allow the evolution of massive stars, galactochemical evolution,

Limb Darkening: Getting Warmer

We present interferometric observations and model atmosphere analyses of three stars: the F-type subgiant Procyon, the A-type supergiant Deneb, and the B-type supergiant Rigel. We use VLTI/VINCI and

Resolving the dusty circumstellar environment of the A[e] supergiant HD 62623 with the VLTI/MIDI

Abstract HD 62623 is one of the very few A-type supergiants showing the B[e] phenomenon. We studied the geometry of its circumstellar envelope in the mid-infrared using the VLTI/MIDI instrument.

Atmospheric NLTE models for the spectroscopic analysis of blue stars with winds

Context. Obtaining precise stellar and wind properties and abundance patterns of massive stars is crucial to understanding their nature and interactions with their environments, as well as to



Radio-continuum emission from the ionized stellar winds of warm supergiants

The Very Large Array has been used at an observing wavelength of 6 cm to survey 25 supergiants of spectral types between B2 and F8. Only one of these stars (Beta Ori, or Rigel) has been detected as a
