Despite more than 30 years of searching, the compact object in Supernova (SN) 1987A has not yet been detected. We present new limits on the compact object in SN 1987A using millimeter, near-infrared, optical, ultraviolet, and X-ray observations from ALMA, VLT, HST, and Chandra. The limits are approximately 0.1 mJy ( erg s−1 cm−2 Hz−1) at 213 GHz, 1 L⊙ ( erg s−1 cm−2 Hz−1) in the optical if our line of sight is free of ejecta dust, and 1036 erg s−1 ( erg s−1 cm−2 Hz−1) in 2–10 keV X-rays. Our X… 

In Search for the Missing Neutron Star Inside of SN 1987 A

Thirty years have passed since the supernova 1987A appeared on the night sky. Despite all observations of the supernova, the remaining core, called the compact object, has yet not been detected. In

NS 1987A in SN 1987A

The possible detection of a compact object in the remnant of SN 1987A presents an unprecedented opportunity to follow its early evolution. The suspected detection stems from an excess of infrared

Indication of a Pulsar Wind Nebula in the Hard X-Ray Emission from SN 1987A

Since the day of its explosion, SN 1987A (SN87A) was closely monitored with the aim to study its evolution and to detect its central compact relic. The detection of neutrinos from the supernova

Additional Evidence for a Pulsar Wind Nebula in the Heart of SN 1987A from Multiepoch X-Ray Data and MHD Modeling

Since the day of its explosion, supernova (SN) 1987A has been closely monitored to study its evolution and to detect its central compact relic. In fact, the formation of a neutron star is strongly

A Three-dimensional View of Molecular Hydrogen in SN 1987A

SN 1987A is the only young supernova (SN) in which H2 has been detected in the ejecta. The properties of H2 are important for understanding the explosion and the ejecta chemistry. Here we present new

The Matter Beyond the Ring: The Recent Evolution of SN 1987A Observed by the Hubble Space Telescope

The nearby SN 1987A offers a spatially resolved view of the evolution of a young supernova (SN) remnant. Here we present recent Hubble Space Telescope imaging observations of SN 1987A, which we use

Three-dimensional mixing and light curves: constraints on the progenitor of supernova 1987A

With the same method as used previously, we investigate neutrino-driven explosions of a larger sample of blue supergiant models. The blue supergiants were evolved as single-star progenitors. The

Nucleosynthesis for SN 1987A from single-star and binary-merger progenitors

We apply the parametrized, spherically symmetric explosion method PUSH to two sets of pre-explosion models suitable for SN 1987A: blue supergiants (BSGs) resulting from the merger of a main sequence

High Angular Resolution ALMA Images of Dust and Molecules in the SN 1987A Ejecta

We present high angular resolution (∼80 mas) ALMA continuum images of the SN 1987A system, together with CO J = 2 1, J = 6 5, and SiO J = 5 4 to J = 7 6 images, which clearly resolve the ejecta (dust



Can a Bright and Energetic X-Ray Pulsar Be Hiding Amid the Debris of SN 1987A?

The mass of the stellar precursor of supernova (SN) 1987A and the burst of neutrinos observed at the moment of the explosion are consistent with the core-collapse formation of a neutron star.

Limits from the Hubble Space Telescope on a Point Source in SN 1987A

We observed supernova 1987A (SN 1987A) with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST) in 1999 September and again with the Advanced Camera for Surveys (ACS)

The X-Ray Remnant of SN 1987A

We present high-resolution Chandra observations of the remnant of SN 1987A in the Large Magellanic Cloud. The high angular resolution of the Chandra X-Ray Observatory permits us to resolve the X-ray

We have been monitoring the supernova remnant (SNR) 1987A with Chandra observations since 1999. Here we report on the latest change in the soft X-ray light curve of SNR 1987A. For the last ∼1.5 yr

Search for a radio pulsar in the remnant of supernova 1987A

We have observed the remnant of supernova SN 1987A (SNR 1987A), located in the Large Magellanic Cloud (LMC) to search for periodic and/or transient radio emission with the Parkes 64 m-diameter radio

Constraints on the luminosity of the central source in SNR 1987A

We obtained constraints on the luminosity of the central source in SNR 1987 A using XMM-Newton and INTEGRAL data. XMM-Newton yields an upper limit on the SNR luminosity in the 2–10 keV energy band,

Constraints on the luminosity of the stellar remnant in SNR1987A

We obtain photometric constraints on the luminosity of the stellar remnant in SNR1987A using XMM-Newton and INTEGRAL data. The upper limit in the 2–10 keV band based on the XMM-Newton data is L X < ∼

SN 1987A after 18 Years: Mid-Infrared Gemini and Spitzer Observations of the Remnant

Using the Gemini South 8 m telescope, we obtained high-resolution 11.7 and 18.3 μm mid-IR images of SN 1987A on day 6526 since the explosion. All the emission arises from the equatorial ring. Nearly


Updated imaging and photometric results from Chandra observations of SN 1987A, covering the last 16 years, are presented. We find that the 0.5–2 keV light curve has remained constant at ∼8 × 10−12
