The S-PLUS 12-band Photometry as a Powerful Tool for Discovery and Classification: Ten Cataclysmic Variables in a Proof-of-concept Study

The Astrophysical Journal Letters
Multiband photometric surveys provide a straightforward way to discover and classify astrophysical objects systematically, enabling the study of a large number of targets at relatively low cost.

Irradiation of the companion star in cataclysmic variables [PDF]

Monthly Notices of the Royal Astronomical Society, 1989
Il est demontre que le rayonnement de l'ecoulement d'accretion au niveau de la naine blanche dans une binaire cataclysmique est incapable de penetrer la photosphere du compagnon. Le rayonnement peut, dans quelques cas, ioniser l'ecoulement d'accretion subsonique juste en dessous du point de Lagrange ...

Partitioned Desires: Female Agency and Interfaith Relationships Around the Partition of India

Gender &History, EarlyView.
ABSTRACT Through an examination of the phenomenon of abduction, I suggest that the preoccupation with women's violation during the 1947 Partition of India has obfuscated a history of female desire. Considering accusations of kidnapping made by women's families against men belonging to a different religion in instances of interfaith desire, I ...

PARALLAX AND DISTANCE ESTIMATES FOR TWELVE CATACLYSMIC VARIABLE STARS [PDF]

The Astronomical Journal, 2008
We report parallax and distance estimates for twelve more cataclysmic binaries and related objects observed with the 2.4m Hiltner telescope at MDM Observatory. The final parallax accuracy is typically about 1 mas. For only one of the twelve objects, IR Gem, do we fail to detect a significant parallax.

Benefitting from brutality? Profits of north‐western Europe's slave trade at the eve of the industrial revolution

The Economic History Review, EarlyView.
Abstract One of the most contentious issues in the study of the Atlantic slave trade is the profitability of the trade. In this paper, we contribute by pooling all available data on transatlantic slave ship voyage accounts into a joint dataset. This dataset includes data from a period of 100 years (1730–1830) and from five nations (Denmark, France ...

Introduction: Charting the Evolution of English and Anglophone Writing in Asia

World Englishes, EarlyView.
ABSTRACT This introductory article explores the history of the English language and literatures in the Asian ‘Outer Circle’ countries, or English in its ‘second diaspora’, focusing primarily on literature from its beginnings to the present. Due to space limitations, the scope is further narrowed to poetry and the novel – the two genres that, arguably ...

On the secondary star of the cataclysmic variable 1RXS J094432.1+035738 [PDF]

Astronomy & Astrophysics, 2002
We present V and Rc band photometry and optical near-infrared spectroscopy of the cataclysmic variable 1RXS J094432.1+035738. We detected features of a cool secondary star, which can be modeled with a red dwarf of spectral type M2 (+0.5 -1.0) V at a distance of 433 +- 100 pc.
