Observations with the Newton X-ray Multimirror Mission satellite show a strong periodic modulation at 6.67 ± 0.03 hours of the x-ray source at the center of the 2000-year-old supernova remnant RCW 103. No fast pulsations are visible. If genetically tied to the supernova remnant, the source could either be an x-ray binary, composed of a compact object and a low-mass star in an eccentric orbit, or an isolated neutron star. In the latter case, the combination of its age and period would indicate… 
The Extremely Long-period X-Ray Source in a Young Supernova Remnant: A Thorne-Żytkow Object Descendant?
The origin of the 6.67 hr period X-ray source, 1E161348-5055, in the young supernova remnant RCW 103 is puzzling. We propose that it may be the descendant of a Thorne-Żytkow Object (TŻO). A TŻO may
The puzzling X-ray source in RCW103
Abstract 1E 161348-5055 (1E) is a compact object lying at the center of the 2000 year old Supernova Remnant (SNR) RCW103. Its original identification as an isolated, radio-quiet neutron star has been
1E 161348–5055 in the Supernova Remnant RCW 103: A Magnetar in a Young Low-Mass Binary System?
We suggest that the unique X-ray source 1E 161348?5055 at the center of the supernova remnant RCW 103 consists of a neutron star in close orbit with a low-mass main-sequence star. The time signature
Because supernova remnants are short-lived, studies of neutron star X-ray binaries within supernova remnants probe the earliest stages in the life of accreting neutron stars. However, such objects
A scenario of the formation of isolated X-ray pulsars with anomalously long period
A scenario of the formation of isolated X-ray pulsars is discussed with an application to one of the best studied objects of this class 1E 161348-5055. This moderately luminous, 1033–1035 erg s−1,
Central Compact Objects in Supernova Remnants
Central Compact Objects (CCOs) are a handful of sources located close to the geometrical center of young supernova remnants. They only show thermal-like, soft X-ray emission and have no counterparts
Aspherical supernova explosions and formation of compact black hole low-mass X-ray binaries
It has been suggested that black hole low-mass X-ray binaries (BHLMXBs) with short orbital periods may have evolved from BH binaries with an intermediate-mass secondary, but the donor star seems to
Deep Infrared Observations of the Puzzling Central X-Ray Source in RCW 103* **
The object 1E 161348–5055 (1E 1613) is a pointlike, soft X-ray source shining at the center of the 2000 yr old supernova remnant (SNR) RCW 103. It features a puzzling 6.67 hr periodicity and dramatic
Evidence for the magnetar nature of 1E 161348-5055 in RCW 103
We report on the detection of a bright, short, structured X-ray burst coming from the supernova remnant RCW 103 on 2016 June 22 caught by the Swift/Burst Alert Telescope (BAT) monitor, and on the
The strongest cosmic magnets: soft gamma-ray repeaters and anomalous X-ray pulsars
Two classes of X-ray pulsars, the anomalous X-ray pulsars and the soft gamma-ray repeaters, have been recognized in the last decade as the most promising candidates for being magnetars: isolated


X-Ray Variability from the Compact Source in the Supernova Remnant RCW 103
A new ASCA observation of 1E 161348-5055, the central compact X-ray source in the supernova remnant RCW 103, reveals an order-of-magnitude decrease in its 3-10 keV flux since the previous ASCA
An Accretion Model for Anomalous X-Ray Pulsars
We present a model for the anomalous X-ray pulsars (AXPs) in which the emission is powered by accretion from a fossil disk, established from matter falling back onto the neutron star following its
Discovery of a compact X-ray source at the center of the supernova remnant RCW 103
A point source of X-ray emission has been detected at the center of the supernova remnant RCW 103 using the Einstein Observatory. The 10 arcsec radius error circle is centered at alpha 16h13m47.8s,
A debris disk around an isolated young neutron star
The discovery of mid-infrared emission from a cool disk around an isolated young X-ray pulsar, which resembles protoplanetary disks seen around ordinary young stars, suggesting the possibility of planet formation around young neutron stars.
Formation of very strongly magnetized neutron stars - Implications for gamma-ray bursts
It is proposed that the main observational signature of magnetars, high-field neutron stars, is gamma-ray bursts powered by their vast reservoirs of magnetic energy. If they acquire large recoils,
A new CCD image of the supernova remnant RCW 103 was taken in 1995 to compare with a photographic plate taken in 1970. We calculated the proper-motion expansion of the outer edge and several
Hot Spot Emission from a Freely Precessing Neutron Star
Recent observations of 1E 161348-5055, the neutron star candidate at the center of the supernova remnant RCW 103, show that a component of its emission varies sinusoidally with a period of
The Evolution of Relativistic Binary Progenitor Systems
Relativistic binary pulsars, such as B1534+12 and B1913+16, are characterized by having close orbits with a binary separation of ~3 R☉. The progenitor of such a system is a neutron star, helium star

Low-Luminosity Accretion in Black Hole X-Ray Binaries and Active Galactic Nuclei
At luminosities below a few percent of Eddington, accreting black holes switch to a hard spectral state which is very different from the soft blackbody-like spectral state that is found at higher
