Sirius B is the nearest and brightest of all white dwarfs, but it is very difficult to observe at visible wavelengths due to the overwhelming scattered light contribution from Sirius A. However, from space we can take advantage of the superb spatial resolution of the Hubble Space Telescope (HST) to resolve the A and B components. Since the closest approach in 1993, the separation between the two stars has become increasingly favourable and we have recently been able to obtain a spectrum of the…

The Sirius System and Its Astrophysical Puzzles: Hubble Space Telescope and Ground-based Astrometry

Sirius, the seventh-nearest stellar system, is a visual binary containing the metallic-line A1 V star Sirius A, the brightest star in the sky, orbited in a 50.13 year period by Sirius B, the

ADONIS high contrast infrared imaging of Sirius-B

Context. Sirius is the brightest star in the sky and a strong source of diffuse light for modern telescopes so that the immediate surroundings of the star are still poorly known. Aims. We study the

SIRIUS B IMAGED IN THE MID-INFRARED: NO EVIDENCE FOR A REMNANT PLANETARY SYSTEM*

Evidence is building that remnants of solar systems might orbit a large percentage of white dwarfs, as the polluted atmospheres of DAZ and DBZ white dwarfs indicate the very recent accretion of

O vi IN THE LOCAL INTERSTELLAR MEDIUM

TLDR
It appears that there is much less O VI-bearing gas than previously stated within the inner rarefied regions of the local interstellar cavity, and there is no strong evidence to support a spatial correlation between O VI and SXRB emission.

Project 1640 observations of the white dwarf HD 114174 B

We present the first near infrared spectrum of the faint white dwarf companion HD 114174 B, obtained with Project 1640. Our spectrum, covering the Y, J and H bands, combined with previous TaRgetting

Establishing HZ43 A, Sirius B, and RX J185635-3754 as soft X-ray standards: a cross-calibration between the Chandra LETG+HRC-S, the EUVE spectrometer, and the ROSAT PSPC

Context. The absolute calibration of space-borne instruments in the soft X-ray regime rests strongly on model spectra of hot white dwarfs. Aims. We analyze the Chandra LETG+HRC observations of the

Detection of the gravitational redshift in the orbit of the star S2 near the Galactic centre massive black hole

The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A✻ is a sensitive probe of the gravitational field in the Galactic centre. Near pericentre at

PRESSURE SHIFT AND GRAVITATIONAL REDSHIFT OF BALMER LINES IN WHITE DWARFS: REDISCUSSION

The Stark-induced shift and asymmetry, the so-called pressure shift (PS) of Hα and Hβ Balmer lines in spectra of DA white dwarfs (WDs), have been examined in detail as masking effects in measurements

Special thanks to Blair Porterfield, Joleen Carlberg and the team at STScI for all their help and advice during the phase 2 proposal. We thank the referee for helpful comments. SRGJ acknowledges

PIERCING THE GLARE: A DIRECT IMAGING SEARCH FOR PLANETS IN THE SIRIUS SYSTEM

Astrometric monitoring of the Sirius binary system over the past century has yielded several predictions for an unseen third system component, the most recent one suggesting a ≲50 MJup object in a

Hubble Space Telescope Absolute Spectrophotometry of Vega from the Far-Ultraviolet to the Infrared

The Space Telescope Imaging Spectrograph (STIS) has measured the absolute flux for Vega from 0.17–1.01 μm on the Hubble Space Telescope white dwarf (WD) flux scale. These data are saturated by up to

RECENT SPECTROGRAPHIC OBSERVATIONS OF THE COMPANION OF SIRIUS

According to the general theory of relativity, light waves originating in a strong gravitational field should have a lower frequency than the normal ones for these radiations, so that the lines in

TLDR
The mass and radius for Sirius B are found to be consistent with the theoretical mass-radius relation for a carbon-core white dwarf.

A comparison of DA white dwarf temperatures and gravities from FUSE Lyman line and ground-based Balmer line observations

The observation of the strengths and profiles of the hydrogen Balmer absorption series is an established technique for determining the effective temperature and surface gravity of hot H-rich white

We have used IUE archive observations to obtain a new and independent estimate of the effective temperature of Sirius B. In this effort we have modeled the observed Lyman alpha profile of Sirius B as
