IPHAS J190812.63+045728.1: A deeply eclipsing, X-ray bright cataclysmic variable with frequent outbursts
Raimundo Lopes de Oliveira, Albert Bruch, Koji Mukai +3
We present a multi-wavelength characterization of IPHAS J190812.63+045728.1. Independently discovered by us after being serendipitously observed by XMM-Newton, followed up with opt…
An extreme case of X-ray reflection in the symbiotic V648 Car
Jherssica Freitas, Raimundo Lopes de Oliveira, Koji Mukai
V648 Car is a -type symbiotic star known for its strong hard thermal X-ray emission, heavy local photoelectric absorption, and stochastic variability. We analyze NuSTAR observat…
Mapping H-Excess Candidate Point Sources in the Southern Hemisphere Using S-PLUS Data
L. A. Gutiérrez-Soto, R. Lopes de Oliveira, S. Akras +18
Context. We use the Southern Photometric Local Universe Survey (S-PLUS) Fourth Data Release (DR4) to identify and classify H-excess point sources in the Southern Sky, combining…
Data Release 2 of S-PLUS: accurate template-fitting based photometry covering 1000 square degrees in 12 optical filters
F. Almeida-Fernandes, L. Sampedro, F. R. Herpich +26
The Southern Photometric Local Universe Survey (S-PLUS) is an ongoing survey of 9300 deg in the southern sky in a 12-band photometric system. This paper presents the seco…
Developing the physical understanding of intermediate polars: an X-ray study of TV Col and V2731 Oph
Raimundo Lopes de Oliveira, Koji Mukai
X-rays in intermediate polars (IPs) originate in a compact region near the surface of a magnetic white dwarf (WD) and interact with the complex environment surrounding the emission…
