    "abstract": "Octet hyperon charge radii are calculated in a chiral constituent quark model\nincluding electromagnetic exchange currents between quarks. In impulse\napproximation one observes a decrease of the hyperon charge radii with\nincreasing strangeness. This effect is reduced by exchange currents. Due to\nexchange currents, the charge radius of the negatively charged hyperons are\nclose to the proton charge radius.",
