Context. Type II-linear supernovae are thought to arise from progenitors that have lost most of their H envelope by the time of the explosion, and they are poorly understood because they are only occasionally discovered. It is possible that they are intrinsically rare, but selection effects due to their rapid luminosity evolution may also play an important role in limiting the number of detections. In this context, the discovery of a subluminous type II-linear event is even more interesting. Aims. We investigate the physical properties and characterise the explosion site of the type II SN 1999ga, which exploded in the nearby spiral galaxy NGC 2442. Methods. Spectroscopic and photometric observations of SN 1999ga allow us to constrain the energetics of the explosion and to estimate the mass of the ejected material, shedding light on the nature of the progenitor star in the final stages of its life. The study of the environment in the vicinity of the explosion site provides information on a possible relation between these unusual supernovae and the properties of the galaxies hosting them. Results. Despite the lack of early-time observations, we provide reasonable evidence that SN 1999ga was probably a type II-linear supernova that ejected a few solar masses of material, with a very small amount of radioactive elements of the order of 0.01 M .

“…SNe are central to discussions of the chemical evolution and star formation history of galaxies, the kinematics of the interstellar medium, the origin of cosmic rays, the production of stellar remnants (neutron stars and black holes), and the determination of cosmological distances. One of the goals of SN research is to gain an understanding of their progenitor stars, which can be achieved by the direct identification of SNe progenitors in preexplosion images (e.g., Van Dyk et al 2003;Smartt et al 2003Smartt et al , 2004 or by using indirect methods, such as statistical studies of the properties of SNe host galaxies and their local environments (e.g., Maza & van den Bergh 1976;Van Dyk et al 1996, and by theoretical modeling (e.g., Woosley & Weaver 1995;Höflich et al 1998;Piersanti et al 2003).…”

To investigate the extent to which nuclear starbursts or other nuclear activity may be connected with enhanced star formation activity in the host galaxy, we perform a statistical investigation of supernovae (SNe) discovered in host galaxies from four samples: the Markarian galaxies sample, the Second Byurakan Survey (SBS) sample, the north Galactic pole ( NGP) sample of active or star-forming galaxies, and the NGP sample of normal galaxies. Forty-seven SNe in 41 Mrk galaxies, 10 SNe in six SBS galaxies, 29 SNe in 26 NGP active or star-forming galaxies, and 29 SNe in 26 NGP normal galaxies have been studied. We find that the rate of SNe, particularly core-collapse ( Types Ib/c and II) SNe, is higher in active or star-forming galaxies in comparison with normal galaxies. Active or star-forming host galaxies of SNe are generally of later morphological type and have lower luminosity and smaller linear size than normal host galaxies of SNe. The radial distribution of SNe in active and star-forming galaxies shows a higher concentration toward the center of the active host galaxy than is the case for normal host galaxies, and this effect is more pronounced for core-collapse SNe. Ib/c-type SNe have been discovered only in active and star-forming galaxies of our samples. About 78% of these SNe are associated with H ii regions or are located very close to the nuclear regions of these active galaxies, which are in turn hosting AGNs or starburst nuclei. Besides these new results, our study also supports the conclusions of several other earlier papers. We find that Type Ia SNe occur in all galaxy types, whereas core-collapse SNe of Types Ib/c and II are found only in spiral and irregular galaxies. The radial distribution of Type Ib SNe in their host galaxies is more centrally concentrated than that of Type II and Ia SNe. The radial distances of Types Ib/c and II SNe, from the nuclei of their host galaxies, is larger for barred spiral hosts. Core-collapse SNe are concentrated in spiral arms and are often close to or in the H ii regions, whereas Type Ia SNe show only a loose association with spiral arms and no clear association with H ii regions.

Discovery of a Light Echo from SN 2003gd

Archival HST/ACS data reveal details of a light echo around SN 2003gd in the galaxy M74, only the fifth supernova around which resolved echoes have been reported. An echo is detected 0Љ .3 from the supernova between position angles of 250Њ and 360Њ, with a fainter signal present at a few other position angles. This material lies ∼180 pc in front of the supernova, with a thickness of 60-120 pc, and may delineate the disk of M74. This structure has a gas density of 1-2 cm Ϫ3 , typical of the interstellar medium; however, the dust grains are smaller than those found in our Galaxy, with maximum grain sizes around 0.25 mm. Since only one epoch of data exists, in two wave bands and with a low signal-to-noise ratio, deeper annual visits should be made with HST and ground-based adaptive optics telescopes.
